I don't mind Blitzkrieg being powerfull as that's somewhat historical but i'm pretty sure Infiltration Assault was never that good.
As for the guy who mentioned some other doctrine trees being useful,the problem is Infiltration is always the best if you have a good tech team for it even as Germany or USA due to cheesy night fighting bonuses.You can't avoid fighting at night and Infiltration will always win a soon as night falls,so every battle has to be started in the morning and has to be over real fast!
:wacko:
