Formation Master. The sergeant can move through the spaces of allies without treating them as difficult terrain as long as it doesn't end its turn in those spaces, and when the sergeant provokes an opportunity attack by moving into an ally's space, that opportunity attack has disadvantage.

Multiattack. The sergeant makes two attacks with a melee or ranged weapon and uses its Command Ally.

Pike. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 8 (1d10 + 3) piercing damage.

Javelin. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Command Ally. The sergeant targets one ally it can see within 30 feet of it. If the target can see and hear the sergeant, the target can use its reaction to make one weapon attack or take the Dodge action.
