The HE part of the HEAT round will do more than firing sabot at them will...
Im trying to remember the different 105 rounds we had for the M-60s.
HEP was, if I remember right, what we were supposed to use against bunkers and Infantry at a distance.
Really hard to hit with a HEP round. It used to curl up and right I think.
They taught us to use the telescope instead of the main sight.
I did run into a guy who shot down a moving helicopter with a HEP round.
I shook his hand. That would be a tough shot.
And we did have the beehive round.
