Interestingly the Sherman had a stabilizer for it's gun. It was supposedly a bitch to learn how to use well and was disabled by most crews but when used correctly it apparently worked fairly well. It might be a nice little upgrade fer an armor doctrine for improved accuracy when shooting on the move. I'll let others work out where it may fit in best if at all but it is a cool thing to think about

Implementing more Buffs to American Armor will make the other Factions less attractive. You can use a Sherman only Accuracy Buff and rename it to Stabilizers.
