I had the pleasure of being in on the 1st field test of the "copperhead" laser-guided round. I don't think it lasted long, too much of a hassle to set up a forward observer with laser sighting for all targets I think.
By the way, the first round fired had a premature deployment of the guidance fins and went end over end and landed about 500 yards away. Should have seen everybody trying to figure out which way it was pointed (it had a shaped charge warhead).
Still firing the heck out of Copperhead. By the way the way the only munition with a shelflife. I have no idea why.
