This is a kind of distillation of my previous hex-and-counter Barbarossa games, onto a standard US wargaming 22x34" mapboard.
Refined Disruption mechanics, including a Both Disrupted (BD) result which reminds me of the old Engaged result in some past games. If the Axis player does not want to exchange, he can accept a Disruption result against the defender instead of a 0.5 exchange result, or a BD result in the event of a 1.0 exchange.
Accept the losses to get a major breakthrough? Luck can be pressed on offense or defense.
Basically corps to army level with selected panzer divisions for small change.
Half-month turns which should play 33% faster than for Death Struggle.
Hidden Russian units. Overall Russian strength may not be known until game's end, and that can affect victory requirements, up or down.
The big if slow Russian mechanized corps are just as clumsily dangerous as ever ... if they exist.
How hard to push? How big a risk to take? ... as historically!
Some solitaire potential on the German side.
