Yeah but not supplying cannister is like leaving the .50 cal off the top, it trashes a tanks ability to defend itself alone against close in infantry.

I would tend to agree, but that was the thinking back then. Also, the basic load of the M1 would have to be re-jiggered. How many HEAT or Sabots do you want to give up in favor of a few Beehive rounds? Plus, Soviet doctrine called for their infantry to be mounted (BMP & BTR's) because they were probably sliming you (Chemicals). You'd kill mounted infantry with HEAT. Frankly, the M1 does need better anti-infantry capability...

Bring back the flamethrower.
