===Imperial Guard===
[[File:Why_Guards_like_Knights.jpg|250px|thumb|left|A little pic worth a thousand words...]] The most competitive option, if tournament lists are anything to go by. Wherever you find the armies of the Imperium, you'll find the Guard in support. That, or you can paint them up in the same colours as your Knight and say that they're his household retainers.

The low cost of Guardsmen means you can bring a decent number of bodies on the cheap, but the most important reason why you want Guardsmen is CP. A battalion (5 CP) of 2x Company Commander and 3x Infantry costs 180. You can take a bare bones brigade (12 CP!) for under 600 points and if you're willing to spend a bit more, you can bring quite a lot to complement your Knights. If you need to shovel CP into a Castellan, Guard is the way to go.

Basic guardsmen with orders can spit out a surprising amount of firepower and can be used to screen, clear chaff, or camp on objectives. Scions are reasonably effective infantry that can be used for deep-striking/grav-chuting in plasma for some high mobility tacticoolness. IG artillery is also great: Mortar heavies weapon teams (HWTs) or Wyverns for anti-horde; Lascannon HWTs, Basilisks, or Manticores for anti-vehicle. Keep in mind that HWTs, although a great bargain, are extremely fragile. As for infantry, keep 'em cheap, dump them on an objective, and hope the enemy ignores them. Guard also has access to cheap psykers in the Astropaths and Primaris Psykers for Deny the Witch and support powers. Furthermore, Guard can bring Techpriests as Elites which is helpful for keeping your Knights alive. Guard armor can be useful as well, sporting weapons that are comparable to many of the weapons the Knights can take, allowing you to specialize your knights more if you so choose. Leman Russes can carry battle and plasma cannons along with a variety of hull- and sponson-mounted weapons to threaten a variety of targets. Hellhounds have GEQ-munching 16" flamer cannons that can negate hit penalties. 

Sir Hektur is an especially good pick for infantry-heavy Guard; he reduces the chances of them fleeing after a failed morale test, and if Canis Rex is destroyed he'll have plenty of screening units to hide behind.
