On G1 I attacked the British BB in the Med. with my BB, Sub from SZ8 and 2 Figs (I know that’s overkill, but I wanted to kill him in one round of battle - which I did).
No it isn’t…
…my friend did the same G1 against me the other day, only with one fewer fighter, and my battleship took out all three German units. Granted, I still lost the BB, but it was nice to take out 33 IPCs worth of gear instead of 10, or 8, or even zero.
So no, it’s not overkill, because that BB, if at all possible, can’t be allowed even a second shot.
As for Brazil, it’s nice if Germany can get there for a round or two, but those troops should really be used to ensure a proper hold on Africa.
I’m guessing the US went heavy in the Pacific, cause otherwise US efforts should have included retaking Brazil and fighting for Africa.
But hey, if your opponent is going to just let you stand on his land, go for it!
