Well, in the version i put forward, i think that only the armor should be allowed to continue-bringing the infantry for a second strike may be a bit too strong (i really don’t know how it would play out-but Russian Buffers could end up failing (miserably)).
Anyway, if it gets some testing, then definately let me know how they work!
Also, expect more constructive criticism as you put more of these great creative topics forward.
I have tested your rule variant and found it too complicated! For example if you want to attack a second turn with the panzers then one might ask one self if is possible to use these tanks together with other units attacking from another territory? All units must do there combat movement at the same time! So any panzers wont be able to make a second combined (with other units) attack! Hmmmm…… I will stick to the Panzergrenadiers advantage instead! 😉
