Soviet production points are created from personnel and arms points; the latter are increasingly available as the war progresses, whereas personnel points, abundant in 1941, become scarcer and by 1944 are not available every turn, often forcing the Soviet player to cannibalise no-longer-needed infantry units for their personnel points (the arms points used to create them are lost). Soviet production is largely determined by the course of the war: the USSR needs to build infantry and antitank units first – although even in the desperate early turns the USSR is still required to build two new air factors each turn, so the Red Air Force will gradually increase in size – then switch to armoured corps and artillery units (which have offensive firepower of ten factors, equal to a German Panzer division) as the tide turns.
