Daunted by Long Campaign force selection

[Lancer]

This thread is full of good information.

I have half a mind to try a Soviet LC on 80x80 or 100x80 then to 100x100

as

1 x fo
1 x 107mm battery
2 x aa truck platoon
2 or 3 x 82mm mortar platoon
2 or 3 x 45mm atg section
1 x BA20 platoon plus maybe 1 x mech scout platoon
1 x scout platoon
3 x rifle company (mg included)
1 x engineer company minus 2 platoons
but maybe 1 heavy tank added - to be a KV-2 when available
1 x T-28 company (or should it be T-26)
1 x BT-7 company - one platoon replaced by motorcycle platoon
and another platoon replaced by a T-27 platoon

The tank company will be changed to T-34 when available and maybe add a platoon. BT-7 will change to T-34 too. The T-27's will become T-60 when available and then maybe SU-87/122 when needed. The force may not be historical but I have no business trying a campaign with a force this large. I am not yet qualified. So maybe that will historical. Especially when in Finland. Could be a disaster or two in the making.
