Russian Heavy Infantry during the later stages of the great war. This is based on an alternative history scenario where world war one never ended, and has dragged on into the 1950s. advances in poison gas technology means that all front line combatants fight in full SCBA attire, using airtight hazard suits, inline air, and motorized filters.
While the October revolution caused Russia to remove itself from the Great, German military alliances with Mongolia and China, and the subsequent Almaty massacre (which involved the almost complete destruction of Tenth October guards under Colonel Joseph Jughashvili) pulled the soviet regime of Leon Trotsky back into the war to safeguard the various southern soviet states. Russian heavy infantry are recruited from soviet soldiers who show particular heroism or legality of the battlefield. It is also commonly thought that heavy infantry are made more effective from the use of various drugs and stimulants, with many members of the elite unit standing at over 6 feet 5 in tall and surviving wounds that would almost always be considered fatal to normal soldiers.
