I'm a fairly new TemplarPlayer. I know I need to get into CC as soon as possible, but what tactics should I use to get there?
While not an actual tactic per se, the bigger your units of infantry the better, especially in the case of Crusader Squads. Templars are one army that can do well without being heavily mechanized so you won't have to feel bad for taking big units of foot sloggers.
Crusader Squads of 20 (10 Initiates, 10 Neophytes) with a meltagun and power fist will cost you 285 points (I think) and when joined by a Chaplain become very, very hard to deal with. Coupled with the Accept Any Challenge, No Matter the Odds Vow these units can steamroll just about any other unit in the game. You'll need to watch for your opponent trying to engage you with multiple squads at once since pretty much no single unit can hope to beat you one-on-one.
Attach a Chaplain (preferably a Reclusiarch) with three Cenobyte Servitors to these kinds of squads. This will allow them to automatically pass their Morale checks by virtue of the Chaplain's
Honor of the Chapter rule and the Servitors will speed the squad along when making
Righteous Zeal moves.
Assuming you start 12" in from your board edge, best case scenario is that you move 6" in your movement phase, run 6" then
Righteous Zeal 6+3" for a total of 33" into the board. You'll be passed the center of the table before the beginning of your second turn in this case, so assaulting the enemy should be easy.
