Introduction
1. HESCO Bastion Concertainer® units can be installed in various configurations to provide
effective and economical structures which can be tailored to protect personnel, vehicles,
equipment and facilities in military, peacekeeping, humanitarian and civilian operations.
The patented design has been subjected to testing with explosive charges up to 20,000lbs.
Correctly configured, a wall made from HESCO Bastion Concertainer® units will mitigate
the effects of truck bomb attack. It has been tested and proven against small arms fire and
RPG, and is acknowledged as the most significant development in field fortifications
since WWII.
2. HESCO Bastion Concertainer® units are delivered flat-packed and is manufactured in nine
sizes from the smallest unit, Mil 2 to the largest unit, the Mil 7. It is constructed with either
4mm or 5mm galvanized steel weld mesh, depending on the cell size and lined with a 2mm
non- woven polypropylene geotextile. (For a more complete and comprehensive breakdown
of the product data, please see Annex A).
Life Saving Blast Mitigation
3. HESCO Bastion Concertainer® units have undergone a huge array of testing worldwide.
This testing has been conducted by the leading authorities in the world in the field of blast
mitigation, containment of blast effects and force protection.
4. The sort of weapons systems used in typical testing has been:
•
Small arms (5.56 - 14.5mm AP)
•
Cannon (20 - 40mm including HE, AP and long rod)
•
Grenades
•
Mortars (81 and 82mm)
•
Artillery (122, 152 and 155mm)
•
Air delivered bombs (US Mk 82)
•
Conventional plastic and home made explosive bare charges. Including ANFO
•
Vehicle delivered improvised explosive devices
5. Due to the nature of some of the testing, specific data is considered classified. Therefore,
an unclassified synopsis of some of the main testing that has taken place over last 13 years
can be found in Annex B.
6. HESCO Bastion Concertainer® units are constantly and continually undergoing testing by
leading authorities. This level and variety of testing demonstrates the pedigree of the
system and the number of different protective uses it can be put to. For example, the
January 2005

system is currently being tested against mortars and rockets and in the near future against
the effects of Hesh rounds. The company has also developed a new overhead protection
system which is scheduled to be tested in early 2005.
Typical Structures
7. The use of HESCO Bastion Concertainer® units is wide and diverse and ranges from civil
engineering with soil retaining walls, flood prevention and the prevention of coastal erosion.
Military uses are considerably more diverse. HESCO Bastion Concertainer® units have been
used in the construction of:
•
Ammo compounds
•
Noise abatement barriers
•
Sentry towers
•
Guard posts, both improvised and in kit form
•
Vehicle barriers
•
Entry Control Points
•
Blast mitigation walls
•
Cover from view
•
Protection from ballistics
•
Protection for aircraft (revetments)
•
Protection of adjacent occupants from the accidental discharge of aircraft weapons
•
Protection of living accommodations
•
Provision of bomb shelters
•
Asset protection
8. The list is not exhaustive. The use that which HESCO Concertainer® units can be put to is
only limited by the user's imagination and a few construction engineering considerations.
9. Examples of typical structures can be found in Annex C.
Fill Material
10. One of the main advantages of HESCO Bastion Concertainer® units is its ability to be filled
with almost any fill material. Only large rocks and clumps of earth should not be used. Fill
materials fall into three categories (very good, good and poor). Very good material would be
well graded sand or gravel with clay being an example of a poor fill material.
11. Comprehensive details on fill material including blast, ballistic and construction
characteristics can be found at Annex D.

Construction Techniques
12. Equipment: There are a variety of equipment types that can be utilized to fill HESCO
Bastion Concertainer® units. The simplest and easiest to use is a front end-loading shovel,
particularly when the structure is below 3.5 metres (11') high.
13. Front end loading shovel size should be selected to match the size of concertainer cell
being filled. The front bucket of a backhoe loader is suitable for all cells up to Mil 1 in size.
Larger 2 Cu m3 (2.6 Cu Yd) buckets can be used for Mil 1, 3, 4, 8 and 9. Loading shovels
with buckets in excess of 2 cu m3 (2.6 Cu Yd) are ideal for the larger Mil 7 and Mil 10.
14. Other loading equipment that can be used:
•
Skid steer loaders
•
Wheeled and tracked excavators fitted with either standard buckets or clamshell grabs
•
Tipper truck/dump trucks fitted with lorry loader grab attachments
•
Concrete skips lifted by cranes
15. Fill Material Requirements: The user of a particular fill material is going to be dependent
on one or more of the following:
•
The type of material available
•
The length of time the structure is likely to be employed
•
The perceived threat
•
The handling equipment available
16. For hastily required defensive positions almost any locally won fill material will suffice.
The only material that should be avoided is that which contains large lumps that may create
voids or damage the cells during the filling operation. Large pieces of material may also
become dangerous pieces of shrapnel. Avoid organic material if possible but it is realized
that in some tactical situations this may not be possible as it may be the only
material available.
17. If during the planning of the structure it is believed that it is to be in place for a time
exceeding 6 months it is essential that a material with good construction characteristics
is chosen. Well graded sand (with low ‘fines’ content), or crushed rock is ideal for longterm structures.
The provision of foundations for long-term structures should not be overlooked. Topsoil
should be removed and replaced with a well-graded crushed rock to a depth of 500mm
(20”) or until all organic material is disposed of. The use of geotextile and geogrids should
be considered. The depth of excavation can be reduced if hard, competent ground is
struck earlier.

18. The expected threat will dictate to a certain extent what material should be used. Sand is
ideal where the threat is likely to be from blast as this will present no secondary
fragmentation. Sand is also ideal for the construction of walls within an ammunition
storage area.
19. The handling equipment will to a lesser extent dictate the material to be used; cohesive
materials do not flow from concrete skips.
20. Placement of Fill Material: Fill material should be placed centrally in the cells. If it is
placed to either side it is likely to topple the concertainer. The material should be placed in
layers of around 150 - 300mm (6” - 12”). It should be spread out by shovel and then
compacted down and into the corners and edges by foot. There is no requirement for
mechanical compaction equipment to be used.
21. It is vitally important that when the first 150 - 300mm (6” - 12”) of material is placed in
each cell that the bottom center is pulled out 25 -75 mm (1” - 3”). If this is not done the
cells will bulge in the center and may become unstable if multiple layers are to be
constructed. This is only applicable for Mil 1, 4, 7, 8, 9 and 10.
22. The following is a guide to the fill material required to fill HESCO Concertainer® Units. It
takes into account swell factors for the cells, compaction factor of the material and an
additional 10% to cover material loss.

23. HESCO Bastion Ltd produces various packages that for ease of use and ordering come
complete and ready to use. All that you must provide is the fill material and the means to
fill the cells.
•
Bunker Package: To construct a 20 foot single entry bunker will typically take 170 m3 of
fill material. It will normally take around 8 - 10 hours to construct.
•
Two-Man Guard Post/Sanger Package: To construct a 2 man Sanger kit will take approx
20 m3 of fill material. This will take around 2 - 3 hours to construct.

24. Calculation of Time, Manpower and Equipment: It is important with any construction task
that you can calculate or estimate the time required to complete the task and also what
resources in respect of filling equipment is required.
25. Many factors will effect the time and numbers of operatives that it takes to construct any
given structure, but the more common ones are:
•
Time of Year
•
Light
•
Availability of resources and manpower
•
Haul distance from stockpile for the fill material
•
Accessibility and ground conditions
•
Type of plant available for your use
•
Tactical situation and threat level
•
Type of HESCO Bastion Concertainer® unit being used
•
Experience of the operatives with the system and the structure being built.
26. The key to working out the quantity of manpower required:
•
Ascertain time available for the construction
•
Calculate the construction time with 4 men and loading equipment
This is your basic construction figure, if you cannot achieve completion within the given
time frame then an increase in manpower and equipment is required.
27. For basic linear construction of a HESCO Bastion Concertainer® Mil 1 unit, of 10m length,
9 cells, allow 20 minutes using one loading shovel and 4 men. This includes unpacking
from a pallet, bouncing the cells out and filling. This is as good a figure as any to use as a
guide figure for basic HESCO Concertainer construction.
More comprehensive guidance on construction timing can be found at Annex E.
28. Maintenance: If the guidance provided in the HESCO Construction Guide for Engineers is
followed then this will avoid the need for any in depth or comprehensive maintenance.
However, for longer term structures, some simple basic maintenance will be required. This
will probably consist of the repair of cells damaged by vehicles, personnel or UV.
Damage to the Geotextile by the UV can be prevented by either the application of HESCO
UV-Cam, cement slurry or the shading of the wall by use of fabric or foliage.
29. Repair: There are two methods of repair which can be found in the HESCO Construction
Guide for Engineers. An additional method would be when a cell is not badly damaged but
January 2005

simply requires some reinforcement. A new cell or unit can simply be placed against the
damaged area and securely attached. The supplied HESCLIPS would be suitable for
this task.
30. Health & Safety: As with all construction tasks the relevant health and safety guidance and
regulations should be followed. Particular areas of risk when constructing HESCO
Concertainer® structures are:
•
Working on structures that are often 14' or higher
•
Manual handling
•
The movement of plant, risk of collision between pedestrians and vehicles
•
Dust particularly in desert environments
•
Working in areas where there is limited visibility, particularly when placing and
compacting material inside Mil 7 and 10 units.
Training
31. HESCO Bastion Ltd can provide training and this can range from a one hour lecture to
comprehensive courses for operatives, supervisors or planners.
32. Courses can be tailored to client's requirements and can also be conducted on site at the
commencement of the project.
Other Considerations
33. There are a number of alternatives to HESCO Concertainer® units when protection is
required. The most common alternative is to use concrete T walls. These walls are quick
and easy to deploy but do suffer from a number of drawbacks, not least the secondary
fragmentation issue.
34. A comprehensive document discussing concrete versus HESCO Concertainer® units is at
Annex F.
35. Another alternative to HESCO Concertainer® units is the ever present counterfeit material.
There are number of counterfeit products available, some purporting to be the genuine
material. They are, in some cases, using very similar markings. The counterfeit
products are far from being as competent and strong as the genuine material. Counterfeit
products are characterised by a lack of UV resistance in the geotextile (typically leading to
excessive premature degradation), and low weld strength, which would almost certainly be
an indicator of ‘one hit protection’, with potential fragmentation hazard.
January 2005

36. Annex G contains phrases that can be used by specifies to ensure that procurement staff
will only buy the genuine material.

SUMMARY OF HESCO BASTION TESTING
INTRODUCTION
1.
HESCO Bastion Concertainer® has undergone a huge array of testing worldwide.
This testing has been conducted by the leading test authorities in the world in the field of blast
mitigation, containment of blast effects and force protection.
2.
The sort of weapon systems used in typical testing has been:
Small arms (5.56 - 14.5mm AP)
Cannon (20 - 40mm including HE, AP and long rod)
Shaped charges (RPG 7 and RPG 18)
Grenades
Mortars (81 and 82mm)
Artillery (122, 152 and 155mm)
Air delivered bombs (US Mk 82)
Conventional plastic and home made explosive bare charges. Including ANFO
Vehicle delivered improvised explosive devices.
AIM
3.
The aim of this document is to summarise the testing carried out on HESCO Bastion
Concertainer® from early 90s to date.
DOCUMENTATION LIMITATIONS
4.
The majority of test information is owned by Military Authorities and in the case of
the British MOD is still subject to the Official Secrets Act. Therefore some critical data has
been omitted to allow a wider circulation of this document.
TESTING
4.
HESCO Bastion Concertainer® was first introduced to the British Military in 1991; it
was then subjected to testing against a wide range of small arms. These tests were conducted
by DERA Fortifications section, (UK MOD research agency) and by the British Army
Infantry Trials Team. DERA Fortifications is now part of QinetiQ
5.
Weapons used were:
a.
b.
c.
d.
Shot gun
7.62mm, single shot and general-purpose machine gun.
0.5” Armour piercing AP, Soviet, 12.7 and 14.5 mm AP
Rarden 30mm long rod penetrator cannon.
6.
The above tests were against HESCO Concertainer® Mil 2 filled with a good quality
fill material. None of the rounds achieved complete penetration of the HESCO
Concertainer®. The Mil 2 at 600mm thick is the smallest unit manufactured by HESCO
Bastion.
1
7.
HESCO Concertainer® Mil 1 Units were also tested against .50" machine gun fired in
bursts of 3 - 5 rounds. The cells were sand filled and no rounds penetrated
8.
The Mil 1 was also tested:
a.
b.
c.
81mm mortar.
155mm HE artillery shell. .
Simulated 120mm HESH round in direct contact.
9.
In 1993 HESCO Bastion in conjunction with the UK MOD developed a collective
protection system (COLPRO). This was to provide protection against 155mm artillery shells.
These were fitted with super quick fuses. The COLPRO system is made up of a 20ft ISO
container protected by HESCO Concertainer® Mil 1. Overhead protection is provided by
steel sheet piles, HESCO Concertainer® Mil 2 and 600mm of soil fill. This test proved that
the COLPRO system would prevent casualties even when the structure was subjected to a
direct hit. This system has subsequently been used extensively around the world to provide
mortar, bomb and artillery type shelters. Shells fitted with delay fuse will cause casualties
with a direct hit.
10.
1995 saw the US military at Fort Leanordwood test HESCO Concertainer® against
155mm artillery shells close into the target of HESCO Concertainer® Mil 3. Damage was
judged to be "superficial".
11.
1997 saw a substantial amount of testing take place both in the US, UK and Germany.
Testing included:
a.
The UK tested the system against RPG7 . Gravel filled HESCO
Concertainer® Mil 1 will approx 90% of the time prevent penetration of RPG7 but
clay fill will not. At least 1.8m of poor fill material is required.
b.
HESCO Concertainer® was tested in the US at Wright Laboratories, Tyndall.
This testing was 235lbs of ANFO, minor damage. 2nd test was an Mk 82 bomb at
fairly short range this resulted in the complete wall moving back a little. The wall was
not breached. The 3rd and last test was over 7 tonnes of C4 explosive to simulate the
Khobar Towers bombing. HESCO Concertainer® was one of 3 wall systems tested;
HESCO Concertainer® faired the best of the 3 with no secondary fragmentation. It
also far outshone the other systems when a cost benefit analysis was carried out.
HESCO Concertainer® was by far the most economical system to employ.
c.
The Germans tested HESCO Concertainer® along with other gabion systems
in 1997. Weapons systems used were similar to previous testing. The results
achieved for HESCO Concertainer® were much the same as previously achieved. The
system was also attacked by anti tank grenades and 82mm mortar in contact. The
damage was judged as “not significant”.
12.
The Dutch Trials Agency, TNO has also conducted trials. This originated with the
Dutch testing the COLPRO system, this achieved the same results as the UK testing. The
Dutch have also recently trialled HESCO Concertainer® for use as ammunition stack
separation walls within large ammunition compounds. This has resulted in the Quantity
distances being reduced, you can now store more, closer together. The test consisted of
5011kg of explosives loaded in 155mm shells in a 20ft ISO container. Live detonators were
then stored within Containers adjacent to the donor. The explosive charge was initiated and
2
resulting in severe damage to the adjacent containers but no sympathetic detonation of the
detonators.
13.
The HESCO Concertainer® system was tested in June 2004 as a vehicle barrier. This
testing was conducted by The Transport Research Laboratory at the request of the UK
security services. Two tests were carried out, the first with two cells of Mil 1 HESCO
Concertainer® filled with a gravel mix. The truck weighing 7500 kgs was crashed into the
barrier at 42 miles per hour. The vehicle was stopped within half a vehicle length. The 2nd
test was with 4 cells with gravel. The vehicle again weighed 7500kgs and travelled at 42
miles per hour. It stopped within 2 metres and was extensively damaged. We have long held
the belief in the company that the barrier system was effective against vehicles but had never
had it tested, these tests have confirmed our confidence in the system.
14.
A similar test has been conducted by ARA in the USA. The vehicle weighed 15000
lbs and travelled at 50 MPH. The barrier was 32 foot in length, 2 with a double thickness
HESCO Mil 1 wall on the base and a single Mil 1 on top. The results were almost identical
with the vehicle being stopped in a very short distance.
CONCLUSION
15.
The above is a quick summary of some of the main testing that has taken place over
the last 13 years that we have been privy to. It can be seen from the above that the system has
been comprehensively tested and continues to be so; further testing on the system is being
conducted by QinetiQ at the moment. This level and variety of testing demonstrates the
pedigree of the system and the number of different protective uses it can be put to.

Time Calculation Guide
1. Other considerations to take into account when calculating additional time are:
To unpack and lay out a 9 cell section of Mil 1 will take approx 3 minutes.
To bounce out further cells and connect to one already laid out will take approx. 2
minutes.
To form corners takes longer. To lay out a section and form a corner from it will take
approx. 5 minutes.
To lay out sections on top of a previously built layer will take approx. 10 minutes; this
includes bouncing out and securing by means of the cable ties or HESCLIPS.
To fill cells at height will take a little longer than that on the floor and whereas cells
on the floor using a medium sized loading shovel will take about 17 minutes with
those only one layer higher taking 20 minutes. An increase in time will be incurred as
the height of the structure increases and in particular when working at excessive
heights.
2. To calculate time we should follow a simple method such as this.
Draw a plan of each structure showing as many dimensions as possible.
Divide the length required by the length of the Concertainer unit to be used to
calculate how many you require. Work on the base first then the second and
subsequent layers.
Calculate the time to form the corners first then calculate the straight lengths.
Calculate the time to fill the bottom layer and then any subsequent layers.
Calculate any time required to cap the top layer to prevent the loss of fill material
3. It will take 4 men to manually fill one cell of Mil 1 and take approx 14 minutes
with the fill being close by.
4. HESCO Bastion produce kit forms that for ease of use and ordering come complete
and ready to use. All that you must provide is the fill material and the means with
which to place it.

HESCO Bastion Concertainer® Units Versus
Concrete T walls in Blast Mitigation
One of the many questions that the HESCO Technical team get asked is
about the comparison between HESCO and concrete when subjected to a
blast load.
The following document is written to address just such a question. HESCO
Bastion was asked to comment on the use of a concrete wall with an internal
wall of brick or block work with the cavity filled with sand. HESCO were
also asked to comment on the difference and in a nutshell, why the user
should use HESCO Concertainer® units and not T walls.
We have made the following assumptions for the purpose of providing advice:
Assumptions
•
•
•
•
•
•
•
‘T’ shaped retaining wall units are 3m high, 1m wide (weight approximately
2T)
Threat is from vehicle borne IED’s (car bomb approximately 250kg
equivalent weight TNT, van bomb approximately 10T equivalent TNT)
Charge standoff from wall 5m (educated arbitrary figure chosen)
UN based design consists of a masonry wall on the attack side of the RC
wall units with a soil infill
Masonry wall be approximately the same height as retaining wall unit
Overall thickness of wall will be comparable to HESCO Concertainer®
design
Blast Protection Provided by Walls
Although materials used in the construction of protective walls can have an
influence on ‘blast’ reduction, generally speaking the geometry of the wall has a
much greater influence. Walls have a finite size, and blast waves will pass over and
around them to the extent that at a certain distance behind the wall, the wave will
have reformed as if the wall had not been there at all in the first place. However,
as you will know the blast wave will now have reduced in intensity due to the
distance that it will have travelled. The distance behind the wall at which the blast
wave reforms is related to the charge size and distance from the protective wall,
and the geometry of the wall itself.
One of the primary uses of defence walls is to generate stand off, it is this which
nd
really provides protection. The 2 reason for the defence wall is to intercept
potentially damaging fragmentation from the device. It is from this aspect that the
concrete T walls are let down. When a concrete T wall is subjected to blast it
almost always breaks up in an alarming way and it itself becomes the weapon.
Fragments of concrete have been found several hundred metres from the blast in
some trials.
It is obviously these 2 last points where HESCO Concertainer units perform far
better than concrete;
- HESCO Concertainer has a proven ability to stop fragmentation; it is after
all a soil mass, this has long been the best way of protecting you from the
effects of blast and ballistics.
- HESCO Concertainer generally remains intact under all but the largest of
attack charge sizes; it therefore does not generate secondary
fragmentation. Even when it has been found to break up (charge size of
20,000lb of military explosives) it still creates “insignificant fragmentation”
HESCO Concertainer® Design
Standard designs are available from HESCO Bastion that will effectively stop a
vehicle bomb from getting close to the intended targets. HESCO Concertainer®
walls are tied together by high strength galvanised steel wire with proven weld
strength between joints to form continuous walls. These when filled with desirable
material (ideally sand or other relatively fine grained cohesionless material) do not
form a significant secondary hazard from either the fill or Concertainer material
itself. They are general considered to ‘fail safe’ i.e. when they do fail (which they
will inevitably do against large threats as mentioned above), they do not contribute
significant secondary hazards.
It has been known for attackers to employ 2 vehicles, one sacrificial to burst through
to allow the second primary device carrying vehicle access to the protected area.
We have trialled the HESCO Concertainer® units against moving vehicles this year
with excellent results, 7500kg vehicle at 42mph stopped within 3 metres with 4
single cells and a 15000lb vehicle at 50mph almost stopped dead by a 10 metre
long wall of Mil 1.
Alternative design
Retaining wall units alone
Against primary blast it is likely that a reinforced concrete (RC) retaining wall design
will have a similar effect on the blast wave from an explosive device as a HESCO
Concertainer design (assuming that the overall geometry is similar in terms of wall
height and length). However retaining wall units are generally freestanding and are
not tied to adjacent units. Such units are less massive than a HESCO
Concertainer® unit wall and under ideal conditions (i.e. assuming that the units do
not break up in any way), car or lorry borne IED’s may turn the units into projectiles
with velocities ranging from approximately 10m/s to over 100m/s (predictions
involve some crude assumptions – see above). In reality however, the units would
tend to tumble as well as break up (the extent to which this would happen
depending on the strength of concrete, degree of reinforcement, standard of
workmanship etc). Both are undesirable in terms of the secondary hazards created.
Reports from servicemen in Iraq indicate that some of the manufacturing of the
concrete walls leaves lots to be desired, we have even heard of instances of
concrete units being padded out with Styrofoam, which means that what you
thought you were getting is far from the reality of the situation. This information is
third hand and has not been substantiated.
Retaining wall/ earth/ masonry wall protective barrier
This idea although theoretically workable would be incredibly difficult to implement,
but more importantly there is still the highly significant hazard from secondary
fragmentation even with a sand blanket between. This wall would most certainly
“fail dangerously” In many cases when this happens you would actually have been
better off without the wall
The practical problems for this idea are:
- You will require a significant foundation for the masonry wall.
- A masonry wall say 3m tall will not hold the required amount of sand fill
unsupported, it will require significant buttressing.
- Workmanship will always be a problem with this type of construction.
- The construction of such a wall will be a significant undertaking, involving
a wide variety of resources which must all be quality controlled and a fair
amount of time, not forgetting setting time for concrete and such like.
Recommendations
- The most effective way to generate blast protection is through the use of
stand-off. The use of barriers is an effective way of achieving this.
- Although HESCO Bastion Concertainer® structures may fail under large
terrorist threats, they do so in a reasonably safe manner. They are also easy to
construct.
- Retaining wall units alone are likely to have a similar effect against primary
blast as HESCO Concertainer® but may not be as effective at preventing the
threat from getting closer to the intended target. They are also likely to produce
a more significant secondary projectile problem.
The retaining wall/ earth/ masonry wall design, although probably the most
aesthetically appealing of the three designs is unlikely to provide any superior
performance against blast and is more than likely to contribute a significant
secondary hazard. It is not an option that I or the scientific community would
endorse.
There are some excellent examples in Iraq where T walls have been used to create
stand off and HESCO Concertainer® has been used to provide the inner defence
wall, this works well.

Specification Requirements For
Soil Filled Gabion Baskets
The requirement is for geotextile lined gabion baskets which are rapidly deployed,
erected and filled which will then provide proven blast mitigation and ballistic
protection to personnel and property.
Specification:
The gabion baskets must be manufactured from heavily galvanised 4 mm steel wire.
Cells in excess of 1.52m x 2.21m x 2.13m must use a heavily galvanised 5 mm steel
wire. The mesh size must be 76.2mm x 76.2mm.
The coil hinges must be manufactured from 4 mm heavily galvanised hardened steel
wire with the joining pins manufactured from 3mm and 4 mm heavily galvanised
hardened steel wire.
The wire must be galvanised to an extent where it will not be affected by the use of a
fill material which has a very high salt content. This would be demonstrated by the
wire being guaranteed for at least 25 years in a marine environment.
The geotextile must be treated with material to resist the effects of UV radiation. The
geotextile should be a 2mm heavy duty non woven polypropylene.
The gabions must be available in at least 9 different sizes to allow flexibility of
protective structure design and use. The system must be capable of being stacked to
allow higher walls to be built.
The gabion system must have been comprehensively trialled and tested by leading
worldwide agencies in the field of blast and ballistic mitigation over a number of
years.
The system must have a proven track record of successful use in arduous
environments. It would be highly desirable if the system were already in use by major
military organisations around the world. This would be demonstrated by the system
already having been designated military stock numbers.
The supplier must be able to supply construction manuals and will with agreement
provide construction training (Possibly subject to extra cost)
The supplier on request will provide guidance on structures to be built to provide
mitigation of specified threats.
