I was a tanker for 7 years. For a real show, you ought to see Tank Table VI on Yano Range at Ft. Knox. I was a gunnery instructor in gunnery skills branch. We taught Armor/Cav Officer basic/advanced course, Pre command course, and sent Mobil Training teams all over the world to train units upgrading to the M48A5, M60A3. We were also working on the at that time XM1. The M60A3 will, or would at that time out shoot the M1 stationary. The M1 comes into it's own moving. The M60 series had add on stabalization, the gun was stabalized, not the sight assembly. So, you (gunner) would have to talk your driver to the best speed (about 12-15 mph)where the sweet spot was-the vibrations from the track pads would harmonize and you could see the target. The M1 has stab gun and sights, so no such problem. The original thermal sights on the A3 were better than the early M1 thermals.
But back to Yano Range, just think of 12-15 tanks parked on line. They are about a foot apart. It is dark, and flares pop. The M85 .50, the M240 coax, and M69 105mm on all of them begin engaging targets! I would be sitting outside on the loaders hatch with a set of headphones on. The muzzle blast would leave you slap happy by the end of the range. But my God, it was fun! Especially when ammo was left over. We, the instructors would load up and show the newly minted Lt's how it was done! You could shoot the 105 soooo fast, it was almost like a 40mm bofors pom pom...
