Editing Warhammer 40,000/7th Edition Tactics/Grey Knights (section)

===Allies of Convenience===

*'''Eldar:''' A decent complement to your army (especially considering how strong eldar are in general now.) Eldar add a lot of speed and damage to a force. However, considering how elite your force is as a GK player, the main thing you need in your allies is more bodies on the field to really hold those objectives.(So look at one of the imperial allies instead)
**One interesting unit is the Avatar of Khaine. Grey Knights have little access to melta weaponry. The Avatar can fire twice his melta weapon. But you don't want him because of that. Check his rules...Daemon! Now your HQ has a 3++ save if you pay 10 points, while the Avatar is near. Cast now Sanctuary. Enjoy your 2++ save! Eldar can no longer use Malefic Daemonology (since, y'know, feeding their souls to Slaanesh on purpose is not a winning survival strategy), so the Avatar is the best way to get an allied Daemon here.
