SD2:M4A1(76)

 is a United States Tank unit in Steel Division II.

Background
M4A1(76) were in storage in Britain during the lead up to the Normandy Landing but Armored Commander did not want them due to tankers being trained on 75mm equipped tanks and not enough time to train them on the 76mm along with logistical issues with the 76mm. Encounters with Heavy German Armour and Sherman losses aroused interest in the M4A1(76). 120 were shipped over to 2nd and 3rd Armored for Operation Cobra.
