1) A storage facility for large ammounts of ammunition for military weaponry.

2) Out of desperation, pitching a growler in an empty ammunition can in the back of your track. Inconsiderate if done while on patrol in a closed track in Afghanistan. Humiliating if your battle buddy takes a picture of it and posts it on the internet.
Bonus points if you close the can and leave ot out for insurgents to find.
1) Adams, go down to the ammo dump and sign out 5,000 rounds of 5.56

2) Spc. Adams took an ammo dump in the back of the STRIKER and gagged the crew out.
