Contra is a freeware modification for Command and Conquer Generals: Zero Hour real-time strategy game and one of the first mods for this game. It adds many new units as well as numerous new upgrades, new general's powers and buildings. It also adds new sounds, maps, bug fixes, enhanced graphics, and other effects, as well as three new generals.
CHINA Tank structures have ammo boxes and crates.
I like the little touch but should probably have shown all of them in 1 image for comparison since the differences are so minor
Would have been too much structures to fit in one picture.
