The intent of the Loose Projectile Restraint System (LPRS) is to provide reusable dunnage on tactical vehicles to contain 155mm or 8-inch projectiles once they have been removed from their shipping pallets at the field artillery firing battery area during peacetime training exercises and in wartime. It is expected that throughout its life cycle the racks will be subjected to direct or indirect natural and induced environments.

The intent of the Loose Round Restraint System (LRRS), is to provide reusable dunnage on tactical vehicles to contain 120mm mortar rounds once they have been removed from shipping boxes but still contained within the fiberboard packing tubes. The tubes are placed vertically into the rack with the tube caps up. Once the cap is removed, the round is accessible directly from the tube or the tube removed from the rack. This action will take place at the heavy mortar firing battery area during peacetime training exercises and in wartime. It is expected that throughout its life cycle the racks will be subjected to direct or indirect natural and induced environments.
