This mod modifies Close Combat III: The Russian Front to allow you to fight the campaign on the Eastern Front as a single unit, the infamous Grossdeutschland. Lead your Battle Group starting as a Regiment in the Barbarossa invasion of 1941, to the bitter end (as a Panzer Korps) at Balga-Kahlholz.
To achieve these ends, extensive modifications to the original game were made. Graphics and sounds were replaced or modified for greater realism. Unit availability is based strictly on what the Grossdeutschland had at it's disposal for the time period and are modelled as close as possible to actual teams, from grenadieres to special tank-hunting groups. Additionally, to improve play against the AI, Soviet teams have been beefed up to 10 men each - Yep, ALL of them - and Soviet armor availablity is increased somewhat over stock RealRed (the data underpinnings of this mod), while German armor availability has been decreased.
