It will depend on whether or not they have something to help them get into charge. if you pay 2 CP's, and still have to make a 9" charge, then I think it's schlock. Granted, yes it helps them with shooting...but...we have Captains for that...but also, there's only one weapon this really affects and that's the Assault Cannon. Heavy flamer auto hits, and stormbolters...I mean...who plops down storm bolters with termies with the intent of really hoping for high damage output?
The article says that this stratagem is good for gunning down squads of massed infantry and I recon that even the lowly storm bolter with 4 shots under 12" could pull that off.
But is that enough reason to spend 2 CP?
