Sweet! The 120 is also electrically fired and we still used the M240. I had one mounted outside my loader hatch and the coax is also a M240. We had the 120mm rounds behind the doors with blowout plates on the top of the turret over the ammo storage. Supposedly the doors would shield the crew as the rounds exploded up and away from the crew. I wouldnt want to experience that though. The Abrams also has rounds in the hull too!
Sorry for getting this off topic. Just a couple of old tankers sharing stories of our cadillacs of the battlefield.
