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

==Knight Errant==
Very similar to the Paladin, though with a Thermal Cannon which is S9 AP1 Melta for chewing up Terminators & Land Raiders.

The shorter range means that it's going to be much closer to the center of the table where it will inevitably start taking your opponent's heavy weapons fire and is also more likely to get drawn into close combat. So it is a good option to make it the Warlord and give him more stamina against enemy heavy weapons and better odds in melee. Either that or use it as a flanking Knight and stalk up one side of your opponent's battle line.

It should be noted that the errant is more effective as an ally knight: Most other armies can do what the paladin does (that is, dakka and crowd pulverizing), while the errant's unique cannon can severely damage enemy's heavy weapons and artillery. Paladin is Spear and Shield, Errant is Greataxe.

With the release of the new codex the Errant can swap its Reaper Chainsword for a Thunderstrike Gauntlet allowing it to hurl any monstrous creature or vehicle it kills in combat. This is also quite fitting since the Knight Errant of old used to come with a large gauntlet. The Errant also gets access to carapace mounted weapons.
