M1 Abrams

[95th Rifleman]

Assuming a 1980's timeline, the M1 at the outbreak of war in december 1986 would of been the M1 variant with the British 105mm rifled gun.

The 120mm variant was in production and as the war escalates and the need for upgunned Abrams becomes more and more apparent I need help in figuring out roughly how many would be refitted and how quickly.
