M103M (USA, Tier-9, HT, premium)
Historical Reference:
During its service from 1957 to 1974, the M103 tank was repeatedly modernized. In the late 1960s, the possibility of installing a 110-mm rifled gun with high ballistics was studied. However, the project did not progress beyond theoretical work, since modernization was considered impractical.
