They are so strong and potent with brens, the replay section is bloated with them being used in that way.
Oh wait, its not, because no one sane uses them that way.
They are most potent in theory.
In practice, if they really were as potent as people here try to claim, they'd be meta long before bren adjustment. Yet somehow they are not.
Care to explain why?
The commandos bren is already the
second strongest lmg in the game, just behind the lmg34, and the commandos can equip two of them.
The main reason people don't really use the Cdo bren is because it's a sidegrade from close range to long range, something the british already have with their tommies (despite the seemingly endless nerf).
The Cdo just lose their favor as ambusher and stealth assault once they exchange the sten for the bren.
