You don't need an AA to defend an IC
Oh yea, brain fart I knew that.
One good use of SBR would be if either Anz/UK had enough ftrs w/in range of a mid sized ��� fleet using an island AB (ftrs) for cover. US could SBR the AB so the ��� ftrs can't scramble. Then the minor powers could drill the ��� navy. The US would have to be willing to loose some ftrs though plus have enough bmrs (that survive) to make the hit. With my luck though I would have two US bmrs left and roll snake-eyes leaving the AB functional.
