Well these are not exactly on target, but maybe interesting for people nothing better to do.
One of the army's technique to open a clear path in a minefield for a column of tanks is to shoot an exploding rope along the path. It's a coil of explosive material that flies out in a straigth line and explodes as it lands, detonating the field mines.
The second one, anecdotal, is exploding MV splices. It is said to happen when taping PILC cables. That is Paper Insulated Lead Covered. If there is moisture trapped during the long and ardourous process of taping it can turn into steam that in turn creates enough pressure to explode the splice or conehead. It could be an old splicer's tale though, heard it on the other side of the ocean first, but also heard it in the States.
