Realizations from my current soviet long campaign

[Imp]

Yeah big games are fun & allow you to have a variety of units while still being fairly realistic.

To realy appreciate maneuvering try a late era main battle tank game. Fast units high hit chances plenty of jockeying for position. Often play them with 40-60 tanks & support. Combined arms is far easier late era due to speed & improved radios you have to be very careful with poor radios as can hit contact & hence moral problems since the radio codes changed in a patch. New ability to press the 5 key & see your company is very handy for maintaining cohesion.
Like WW2 adapting tactics to your sides abilities is vital.

A note cavalry are size 2 units & fast so vulnerable
