The Soviet army had plenty of manpower during WWII. That includes not just the frontline troops, but also all the various support units that helped the Red Army turn the tide of the war. Battlefront has a new wave of these support units available now for Flames of War.
Il-2 Shturmovik Assault Flight (SBX77)
The Ilyushin-2 Shturmovik ground-attack aircraft was one of the most important Soviet combat aircraft of World War II. The Il-2 was a well-designed, effective aircraft and was produced in great numbers.
ZSU M17 AA Platoon (Plastic) (SBX78)
Units sometimes received ZSU M17 MGMC lend-lease half-tracks fitted with quad .50 cal machine-guns. These light anti-aircraft weapons were often enough to deter the few remaining German tank-busting aircraft that roamed the skies over the front
Heavy Tank-Killer Company (Plastic) (SBX71)
Motor rifle brigades fielded the 57mm and the 76mm ZIS-3 gun as combined direct-fire artillery and anti-tank weapon. While not as mobile as the 45mm guns, the 76mm had the penetration and firepower to deal with a wide range of targets, and the mobility to accompany the infantry in attacks.
Light Tank-Killer Company (Plastic) (SBX70)
The 45mm obr 1942 gun is the standard Soviet anti-tank weapon, with each motor rifle battalion fielding a small company of them. These small, light-weight guns keep enemy medium tanks from assaulting the infantry and pick off unwary tanks that expose their flanks.
