Editing Grav-Weaponry (section)

===In 7e===
Grav-guns are something of an alternative plasma gun in terms of use. It has [[MEQ]] and [[MEQ#TEQ|TEQ]] killing potential comparable to plasma, without the chance of blowing up and if they stand still they get a extra shot. However, this comes at the cost of shorter range (which is further shortened by moving due to Salvo) and a weakness to light armour which makes them worthless against Guardsmen, Ork Boyz, and the like. Because of this grav-guns are best used at mid to short range, prioritizing heavy units to get the best use out of them. Also capable of tearing through vehicles when used in large numbers via hull point stripping that can be argued to both ignore a vehicle's cover save and deal two hull points worth of damage for every six after the first.

Essentially, grav guns are meant for killing the big, tough units in an enemy army while leaving the fodder for the rest of your army to handle.

Unfortunately, as a consequence of high RoF and AP values combined with a simply peerless anti-vehicle capacity, grav-weapons, specifically grav-cannons for space marines, single handedly shattered the relevance of vehicles in 7th edition. Statistically, a grav devastator squad pays approximately 51 points per glance for any armour value, where lascannons pay 60-210 points over the ranges of armour 10-14.
