How should a two-person unit specify an ammunition chest?

Answer: Match the lock to the custodians, not the floor. Two custodians means dual locks, one means a keypad plus key; a 1200 mm three-tier unit at 85 kg suits either.

How many units fit in one room?

Answer: Divide annual holding by unit volume, add one spare compartment, keep rows at six or fewer.

Can a vehicle unit serve as a depot cabinet?

Answer: Briefly, not long term. Two tiers and 180 L held only by lashing give poor standing stability.

Does a duty-room cabinet need dual custody?

Answer: It depends on control level and handover rate; high-turnover posts do better with a keypad.

Can all five sites share one specification?

Answer: Rarely. Any variable moved toward depot practice costs efficiency elsewhere, so one family with several sizes is the compromise.

Where an Ammunition Chest Is Used: Five Site Configurations

Quick answer: An ammunition chest is sized by three questions, not by floor area: how long the stock stays in place, how often the door opens, and how many people hold keys. A depot wants 1800 mm rows, a duty room a 1200 mm cabinet with keypad access, a range store a door clearing 90 degrees, a vehicle mount four-point lashing, a temporary site a knock-down frame.

FAQ

1. How Ammunition Chest Requirements Differ by Site

The same ammunition chest behaves differently in each room. A depot counts by compartment in rows, a duty room holds only the shift batch, a range store must be reachable from the threshold.

Height moves first, then tiers, then locks. Depots run to 1800 mm, duty rooms stay under 1200 mm so the top plate is visible from a chair, vehicles stop at 900 mm. Tiers fall from six to two, and locks run from dual custody to a single keypad.

Opening frequency explains the rest. A depot door opens three times a day and can carry a heavy leaf; a duty-room door opens a dozen times a shift and needs one-handed locking; a range store is hammered for half a day, where hinge life beats wall thickness.

Site	Height	Tiers	Locking
Depot floor	1800 mm	6	Dual custody
Duty room	1200 mm	3	Keypad plus key
Range store	1500 mm	4	Padlock and seal
Vehicle mount	900 mm	2	Latch with catch
Temporary site	1600 mm	5	Padlock

2. Depot Floors: Rows of Floor-Anchored Units

A depot unit is 1800 by 1000 by 500 mm, six shelves pitched at 250 mm, 120 kg per shelf, with 60 mm between cabinets so doors clear 180 degrees and an 800 mm aisle beyond six units.

Fixing is not optional: one M10 anchor per corner and two wall ties. Where floor flatness is off by 3 mm, shim first, or the door weight loads the hinge and the top gap opens within a year.

Most depots run dual custody, a keyed cylinder with the duty officer and a padlock with the storekeeper, over a 40 mm door stiffener carrying the bolt hole.

3. Duty Rooms and Temporary Sites: Smaller Units

A duty-room ammunition chest compresses to 1200 by 600 by 450 mm, three tiers of four compartments, near 85 kg, light enough for two people to shift and heavy enough that one cannot walk off with it.

The keypad plus mechanical key gives dual control, the code changes each shift, and the battery box belongs inside the door.

Temporary sites use knock-down frames joined by clips and bolts, 65 kg per unit, six standing in 20 minutes. Without anchors the frame leans on a rear brace and row interlock, on 100 mm bearers with desiccant renewed every 20 days.

4. Range Stores and Vehicle Mounts: Doors and Shock

Range store doors swing 180 degrees on three hinges with three bolts each, 900 mm wide, the working tier at 900 to 1400 mm. Where the aisle is under 1.2 m, double doors at 450 mm halve the radius.

A vehicle-mounted ammunition chest is 900 by 500 by 400 mm, two tiers, a 10 mm mat under the base, four-point lashing at 45 degrees on straps above 2 tonnes, and latches with a secondary catch.

Item	Range store	Vehicle mount
Door	180 degree, 900 mm	90 degree or top
Tiers	4, working 900 to 1400 mm	2, weight low
Fixing	Floor and wall bracket	Four-point lashing
Shock	5 mm rubber feet	10 mm base mat

5. Comparing Configurations Across the Five Sites

The depot buys capacity with height, the duty room speed with capacity, the range store clearance with structure, the vehicle mount fixing strength.

Sizing runs in order: height against ceiling and sightline, tiers against item size and posture, locks against handover rate. Then 1.2 to 1.5 mm cold-rolled sheet with powder coating covers all five indoor cases.

Floor condition is the item most often missed: depot slabs take an anchor, tiled duty rooms need a chemical anchor, and a vehicle floor cannot be drilled at all.

Conclusion

The five sites answer three questions: how long the stock stays, how often the door opens, who holds the key. Depots need stability, duty rooms speed, ranges clearance, vehicles restraint, temporary sites disassembly. Match those words to the room and the ammunition chest becomes a calculated specification.
