weapons and ammunition were stolen in america during the vietnam war. ive seen accounts of us troops opening up doors in a jungle bunker and finding entire pallets of american made ammunition, in the original packageing that left the factory. soemtimes the original factory invoces were still attached.
same with guns. lots of stolen guns were found in the jungle.
it happened then, it can happen now. do you really think the government is going to let "semi loaded with 90,000 pounds of ammunition stolen" hit the front page or 10 pm news?
