I loved the M1. At Knox we trained in both M60s and M1s. Stand on top of an M1 and look down, and you can see the welding seam where the turret’s forward armor is attached. It looked to me like a good two feet of armor forward of that seam. Then I’d get in an M60, and see that the turret armor was more like four inches thick. Felt like I was sitting in an eggshell. Same thing with ammo. In an M1, ammo is behind a sliding armored door, and the ammo compartment has a blast panel on top so if you get hit there, the blast goes up instead of into the crew compartment. In an M60, the ammo was literally stashed EVERYWHERE inside the turret. Being in an M1 made me feel superhuman. In an M60, I felt like I had the offensive punch of an M1, but could be killed by anybody with a Ma Deuce.
