Unfortunatly if you have a bren squad in the Roo with a piat squad, the piats and bren will not swap seats that means that a good half the time you need to spend rotating the roo's facing so that the piats will fire or sometimes the brens take all the seats but one leaving only a single piat firing.
Not true at all, since the brens won't be doing any actual firing whatsoever, and the PIAT's 105 priority to fire against tiger armour means they will always pop their heads out to shoot at the thing.
sorry but lets put it this way if KT + PAK > ROO + PIAT + BREN
THEN ROO =/=OP
So, you're saying that 1300 MP 120 MU 680 FU 22 pop > 735 MP 210 MU 150 FU 15 pop equals the roo not being OP?
I'm somewhat at a loss of words here, considering that the roo would not be guaranteed defeat versus that combination.
