Hello, former US Army tank crewman here
I wanted to point out that the M60 series was NOT capable of firing M900 APFSDS rounds, as it was only capable of firing M735, M774 and M833. The M900 round was only authorized for use in M1 tanks and MGS platforms. Firing the M900 from any other 105mm tank system would result in a failure of the gun mount, the recoil mechanism seals, and a catastrophic failure in the gun breach.
This is my first bug report form, so I apologize in advance if I did not fill it out correctly
