I think Panzerblitz helps a bit against Russia in the way you can move in with heavy support from tanks an then move em back when the territory is captured in a safe distance. However I do think The German player is in a bigger need of mobility for his infantry. Therefore I suggest one to replace Panzerblitz with any of my NA variant of Panzergrenadiers, especialy for those who thinks Panzerblitz sucks!
1. Panzergrenadiers
During World War II, the Germans had troops that were designed for fighting alongside tanks. These were fully motorized units, so that they could at all times keep up with the tanks.
Each of your tanks give one matching infantry one additional movement allowance. The tank and the infantry unit must leave from the same territory.
2. Panzergrenadiers
The Germans used elite troops that were designed for fighting alongside tanks, favoured with a greater proportion of the best equipment. These troops were fully motorised units, so that they could at all times keep up with the tanks.
Each of your tanks give one matching infantry one additional movement allowance and an increased attack capability of 2 or less in the first cycle of combat only. Even if supported by artillery, their attack remains 2. The tank and the infantry unit must leave from the same territory.
3. Panzergrenadiers
The Germans used elite troops that were fully motorised. These troops were designed for fighting alongside tanks and favoured with the best equipment.
Each of your tanks give one matching infantry one additional movement allowance and an enhanced defense capability of 3 or less. This increased defense ability is for the first cycle of combat only.
