River hex-sides do not obstruct strategic land movement. Open sea, frozen or unfrozen lake, and impassable hex-sides do. The Russian Player may strategically move as many as 3 non-front units. An odd number eliminates a unit attempting to sail through a sea under enemy control. A Russian replacement unit enters the game on the Eastern mapboard edge or on any city or town which could be a terminus for strategic movement at that instant.
German replacements enter on Warsaw, Helsinki, or Bucharest.
Unlike reinforcement units, new replacement units are Dispersed. Not more than 1 unit may arrive in a hex as a replacement or strategically moved unit, per turn. Armor replacement factors must be used to replace armor or mechanized units. All Axis ally units and German armies are irreplaceable. No more than 2 Russian front units may enter the game as replacements per turn.
