@Igor: When the staff officer misses his command roll, the brigade general can still give any orders.
We use a houserule that gives infantry units a -1 to hit if it moves more that 12″ in line formation. The point is, that moving fast in line formation was rather difficult.
A russian Army Commander can command a division as per page 26. If the division as one or two brigades there is no penalty. If it has three brigades he ist at -1 Staff Rating, if four he is at -2 Staff Rating.
He con only command several brigades wit one order if they belong to the same division.
AT vol. 2 is only for AT Vol. 2. We allow one army commander and if there is more that one division or corps in the army an additional corps commander for rerolls.
+1 hand to hand means one additional hand to hand attack.
