Are these munitions not safe enough to use for training? (Depending on age and condition of course.)
yup an excuse to blow things up for the hell of it
but seriously,3 million tonne? it'll take your(and mine) generation to empty the damn pile down till the last round
i think it's better to recycle it(there's iron,copper,brass,aluminum,lead,etc)...it's more cost effective to recycle stuff than to mine it
