They also figured out that if you put ice down a mortar tube, it delays the launch so that the terrorist scum are long gone when the mortar comes out of the tube and our military can't vector in on them.
It's got to be a chore for our forces just to stay ahead of their nasty, deadly stunts.
wouldn't the mortar just slide down the tube as the ice mels and nestle at the bottom?.I thought it (mortar)needed to be dropped to trigger the firing pin/cap.
