You gotta hand it to the inventive Danes -- "New LWAC Ammunition Case Heralds Revolution In Military Ammunition Resupply."
A recently tested lightweight small arms ammunition case is on display on the PPD stand, S7-261, during DSEI. Utilising composite materials and innovative design it reduces the weight of a standard NATO ammunition case by 70% and increases the number of rounds that can be carried on a standard NATO pallet by 10%. . .PPD’s LWAC can be safely packed and stowed with no requirement for modification to platforms, stowage systems or weapon mounts. Different colours can be incorporated into the composite LWAC case to signifying the type of ammunition within it, blue= training, green=operational etc. As the LWAC cases can be made transparent, still with the colouring pigment, the number of rounds can be counted without having to open the case saving time during stock checks. An RFID tag can be built it allowing each case, its content and its movement to be tracked from the moment the LWAC case is made to the moment it comes out of service.
And if you pick up one of these on the battlefield, you'll need those light weight ammo cans: From South Africa comes the iKUNZI PAW 20. The semiauto Personal Area Weapon fires 20mm x 42B ammunition from a Four round box magazine at a range out to 1000m. It’s no lightweight, coming in at 6.8kg.
