Martial Advantage. Once per turn, the commander can deal an extra 11 (2d10) damage to a creature it hits with a weapon attack if that creature is within 5 ft. of an ally of the commander that isn't incapacitated. 

Multiattack. The commander makes three longsword attacks. 

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Heavy Crossbow. Ranged Weapon Attack: +4 to hit, range 100/400 ft., one target. Hit: 6 (1d10 + 1) piercing damage.

Leadership (Recharges after a Short or Long Rest). For 1 minute, the commander can utter a special command or warning whenever a nonhostile creature that it can see within 30 ft. of it makes an attack roll or a saving throw. The creature can add a d4 to its roll provided it can hear and understand the commander. A creature can benefit from only one Leadership die at a time. This effect ends if the commander is incapacitated.
