It has PPSH Shock Troops. I don't think there's anything to suggest a Shock Army had more SMGs than other armies. The main point of a Shock Army was to be fully equipped by itself for attacking enemy armies and breakthrough, by reinforcing them with more armored and artillery assets than other armies. The new line-up represents that.
From a gameplay perspective having SMG mainlines in the same commander that already has an SMG elite is simply redundant. AVD is there now as a useful tool, but mostly to balance out the strong combo of premium medium + elite infantry + strong offmap.
Sander any chance to Return the IL2 loiter to any doc. There is only 1 doc with that ability now. Where's OST have 3 commanders with JU87 loiter. It would also be pretty good to remove loiters from OST as well.
