Editing Warhammer 40,000/7th Edition Tactics/Space Marines (section)

====Tactics====
Close Range Bolter Drill turns the army into a close quarters shooting monster, the opposite of the Tau who want to stay away from the enemy. Get into that golden 12" range to make the most of twin-linked bolters, but be wary of melee specialists who also want to be that close, in order to charge (at least your Overwatch is a realer threat thanks to CRBD). While your dudes getting so close wastes the range of most heavy weapons, keep in mind heavy bolters also benefit from CRBD, and are thus worth consideration in spite of your preferred range of point-blank. Play like Aspect Eldar and keep your Troops units focused on destroying infantry, using your extra Centurions to deal with armor. Flamers and meltaguns merit consideration since you want to be close anyway, as do bolter Scouts since you can Infiltrate + Scout into rapid-fire range from the word Go.
