Those look pretty good . Could even find uses for them on other vehicles as well , not just the Jeep . You seem to have a mix of US ( entrenching tool & helmet ) and British ( small pack ) personal kit . Might be better to keep the large pieces of gear generic , like the ammo cans ( 50 cal used by US , Brits , even the Russians ), gas can , crate and tarps . Make the country specific stuff separate so it can be used to accent a variety of vehicle types . Or just make generic large pieces , the modeller can add his own bits to compliment his army of origin
