Sergeant Willard is the Human commander of an M1A1 Battle Tank squadron and a human hero, at least in the tutorial. His special tank is an experimental tri-barreled gatling tank, stronger than others and able to dish out more damage. The tank is called Thumper.
Biography
Woolard is called in to support Colonel Moore's forces when they rescue The President. Moore is surprised at this, because Woolard had been retired from service for some time. Moore figures that Woolard was called back because of how badly the fight was going, but in reality Woolard volunteered for service and managed to commandeer Thumper.
After evacuating the President, Woolard stays back to keep the Habitat Walkers and other forces away from Moore and the President. Moore has more faith in Woolard now, and trusts him with the information that the Joint Chiefs are dead, the Vice President is hiding in a bunker, and the United States' armed forces may have suffered up to 90% casualties.
Special Abilities
He has one special ability, Saturate Area. When Saturate Area is activated, Thumper spins its firing barel up and rapid-fires many shells into the selected area. The attack is inaccurate but incredibly devastating against any enemy unlucky enough to be in the target area.
Inspiration
Developers' posts on the forum indicate that he was named after the protagonist of Apocalypse Now, Captain Benjamin L. Willard, who was played by Martin Sheen.
Woolard's tank, Thumper, is named after a character from Bambi.
