So I am reading how this new round will replace four different types of rounds for the M1 Abrams main gun.  Just how many different rounds are there for the Abrams main gun?  Having never thought about it, I was interested to see that there are at least four.

Shucks. I was hoping it would contain some kind of pork product.

I guess I have heard of 3 of those.  I didn't know they had a main gun round that was anti-aircraft.  Does that mean it has a proximity fuse or just a timed/distance fuse?

Which round do they use for emergency, non-parachute drops? Does this new one replace that?

When I was in, there were two "warshots"  APFSDS (Armor Piercing Fin Stabilized Discarding Sabot) AKA - Sabot round.  Used for Killing Tanks.  Depleted Uranium Long Rod Penetrator. And HEAT (High Explosive Anti-Tank) AKA HEAT round. For other vehicles (Can be used on Tanks, but Sabot rounds work better.)  There were blue training rounds for both (eg, the SABOT training round was only steel.  I have one in my garage.  I also have a training HEAT round, big chunk of metal.  Used for punching holes in green-painted plywood cut to look like Soviet tanks and APCs.)

There was a lot of lamenting the loss the of the 105mm Beehive (Anti-Personal) round from M60A3.  Nothing like having a 105mm shotgun.   So it took until 2005 for the Army to complete development of a 120mm anti-personal round...since, you know, we only had a 105mm one      And there were rumours of anti-helicopter round after the demise of the Sergeant York DIVAD system.
