Line Tactics. The soldier has advantage on attack rolls against a creature if at least one ally is within 5 feet of the soldier and isn't incapacitated.

Fearless Faith. The knight is immune to being frightened.

Crusher. Once per turn, when the knight hits a creature with an attack that deals bludgeoning damage, the knight can move the creature 5 feet to an unoccupied space, provided that the creature is no more than one size larger than the knight. Additionally, when the knight scores a critical hit that deals bludgeoning damage to a creature, attack rolls against that creature have advantage until the start of the knight's next turn. 

Divine Smite. The knight channels the holy light, making its attacks deal an extra 2d8 radiant damage.
