A medium-sized, cylindrical metal canister designed for holding flammable gas, featuring a robust steel construction with a slightly weathered and scratched surface to indicate field use. The canister has a prominent valve at the top with a red or yellow safety cap, and warning labels with hazard symbols and text are prominently displayed on the sides. The body is painted in a muted olive green or industrial gray, with areas of rust and wear showing through, adding to the realistic military aesthetic.
