The Leader of Men, often called a Commander, is a warrior that leads his fellows from the front, and is a force for them to rally around.

Rally The Troops

At 3rd level, when you use your Second Wind, you may apply the benefit to a number of additional allies equal to 1 plus your charisma modifier that are within 60 feet of you.

Inspiring Shout

At 3rd level, you learn to shout orders across the battlefield.  You can use the Bolster and Charge shouts.  At 7th level, you gain the Shake it Off shout.  At 10th level, you gain Own the Battlefield, and at 14th level you gain Stand Tall. You may use this ability once, plus one additional use per point of charisma modifier per short or long rest.  The shouts features are as follows:

Bolster

One ally within 30 feet gains 1d10 + your fighter level in temporary hit points.  At 18th level, this applies to a number of allies equal to your charisma modifier (minimum of 1).

Charge

One ally within 30 feet may use his reaction to move half of his movement.  If this movement ends with the ally within 5 feet of a creature, the ally may make a melee weapon attack against the creature.  At 18th level, you may affect a number of allies equal to your charisma modifier (minimum 1).

Own the Battlefield

Each ally within 30 feet of the Tribal Champion Gains advantage on the next attack it takes before the end of its next turn.  In addition, the next attack made against the ally has disadvantage.

Shake it Off

One ally within 30 feet may make a saving throw to end an affect it is under (if the affect allows a save).  It gains a bonus equal to your charisma modifier on the save.

Stand Tall

Each ally within 30 feet gains resistance to bludgeoning, piercing, and slashing damage until the end of its next turn.

Champion's Influence

At 7th level, you gain additional skill in inspiring your fellows.  You gain proficiency in either the Persuasion or the Intimidation skill, and you add twice your proficiency bonus to either skill.
