I was mulling over some possible Raven Guard tactics, ran some numbers, and I believe I may have hit upon an interesting alpha strike build. I'm just not sure if it is too bold and risky or not.
Deployment: Deploy two or three Rhinos full of Tactical Marines 12" from your board edge.
Scout Move: Move your Rhinos up 12" (You are now at the center line of the board).
Turn 1: Move your Rhinos up 6" and flip them around so that the rear faces the enemy.
Disembark the Tactical Marines up to 6" from the rear ramp (which is now facing toward the enemy).
Proceed to Rapid Fire any enemy that isn't hugging the back table edge since you are now standing 12" from the enemy's table edge.
Profit!
It seems hard to believe, but with the Raven Guard Chapter Tactics you can give "Scout" to Tactical Squads in Rhinos and have a nice firing line pumping our Rapid Fire Bolter rounds into any enemy on the board on turn 1. That seems like a pretty good ability to me.
It seems to me that you should concentrate fire on their shootiest squads (to cut down on return fire coming your way). Plus, you have stealth for the first turn so that might help a little. You can ignore the big scary enemy dedicated close assault units since they aren't allowed to charge you until turn two.
So what do you do on turn 2 when you get charged by the enemy assault units? By that time your two to three assault squads with Jump Packs have had time to move into position and can assault anyone who is stuck in close combat with you. This way you don't have to worry about losing your Assault Squads to Overwatch fire.
The game should be decided in two to three turns. After that it's all over but the crying. It seems to me that the only hard counter to this tactic is a lot of 'mech or judicious use of cover or fortifications by the enemy. If you see that kind of setup in front of you you will have to play a more conservative game. But if they have left themselves open to the Raven Guard Alpha Strike Build then by all means show them the error of their ways. What do you guys think?
