If an OKW player, with OKW being in its current state, makes it to a KT, you have done something very wrong lol.
If you can't field KT as OKW player with OKW current state, YOU do something terribly wrong, like forgetting how to micro or getting base locked despite having more units on the field.
God, why its always "everything follows this rule, unless british"
Actually, it always was "everything follows this rule, unless OKW" up until last patch.
British here give up mobility for the firepower.
Soviets being soviets, cheap and ineffective unit.
3 remaining armies have very reliably AA that will make a short work of anything that invades sky, USF M15 and OKW AA HT being the most effective in the game for the cost(if we exclude a pair of 222s, which are also reliable AA).
