Well, my friend Chaos insists on reading what he wants, or seems to want.
What I meant with my 8 hex stop, was, was, yes as you imagine, deploy the 16 grxxx in 8 hexes in a nice straight line, way out in the open, by themselves, no picket, no back-up, flanks wide open, no reserves. And a great big sign that says "please eat me".
'42 rxxx is 20 AP's. Plus a few for attachments.
The 8 hex stop was in response to Matt, who is trying to defend Moscow. Not to be used in the South.
River lines and terrain seems obvious, I thought, to everybody, so I saved myself a little typing time by not including this.
Have noticed that you have gotten more specific with your comments, a good thing.
What I have not seen is any comment on setting up rifle brigades in a command structure, ie, with hq and sappers. this gets better cv and digs faster. And, since the hq will be under Straka, you can move the Stravka HQ within 5 and get the benefit of massed sappers in Straka, gamey as hell.
Bonus, the "cut points", in morale, for reduced movement costs to enter ezoc are 56,71,86. If you ask real nice I will provide the manual source, or somebody else can provide. This matters, especially since you may not what your pickets to be brushed aside by hasty infantry attacks. Example, only the very best German inf (morale over 85) can hasty from 5 clear hexes, that would be 10 MP's burned to advance "to contact" then three (I think) for the hasty. That's in clear weather, so for the cold turns, the picket line can be closer.
Players should have 16 cav xxx by Dec '41, cost is 5 AP each, just don't lose the cav xx which come along as reinforcements. A few more trickle in early '42. That's going to be a lot of cav xxx, really cheap, not as mobile as txxx, but much, MUCH, more powerful.
