1503-1575. Sarge and the Bucket O' Soldiers

Sarge (also known as Army Sarge and Sergeant), is the gung-ho commander of an army of plastic toy soldiers from Bucket O Soldiers and loosely based on his voice actor's role as Gunnery Sergeant Hartman in Full Metal Jacket. Sarge is voiced by R. Lee Ermey in all three films.
In Toy Story, he and the Bucket O' Soldiers are set in particular positions. They are highly disciplined with a "Leave no man behind" policy and are masters of reconnaissance. Woody describes them as "professionals." The soldiers venture out of Andy's room and hide in an indoor plant to report Andy's birthday presents to the toys and one of his comrades was injured after Mrs. Davis accidentally steps on one of them. They announced the first few presents, but didn't get to tell Andy got a Buzz Lightyear action figure. Sarge and his soldiers thought Woody was a murderer when he knocked Buzz off the window, so they "frag" him and each one of them attack Woody, along with the other toys. In the moving van, the soldiers attack Woody when he pushed RC off the van, making Sarge and the toys think he's murdering him now. However, Sarge sees that it was an accident Woody knocked Buzz off the window and is proud to work under Woody once again, as shown at the end of the film when they hide in a Christmas tree to report to the toys what Andy and Molly are getting for Christmas.
In Toy Story 2, Sarge and his soldiers role is very minor. He first orders the soldiers to keep looking for Woody's hat in the toy box. When Buster was about to come to the room, Sarge and his army held back the door (with help from Rocky) to prevent Buster's entry, but Buster bursts open the door, causing the soldiers to go flying everywhere. When Woody alerts the toys about the yard sale occurring outside the house, he signals Sarge for an "emergency roll call" and Sarge orders the toys to line up in a single-file line. At the end, Sarge and his soldiers watch Wheezy sing "You've Got a Friend in Me".
In Toy Story 3, several years after Toy Story, only Sarge and two of his men are seen. Woody ordered Sarge and his men to retrieve the phone. That plan, however failed. Knowing that Andy is going to get out the trash bag, Sarge and his last two men (who have attached parachutes) leave Andy's room to find a better life. Buzz believes they are going AWOL, but Sarge claims that their mission is complete, and that when trash bags come out, the Army men are always the first to be thrown away (it is likely that the rest of the soldiers had left prior to that day). Before they leave, Sarge tells Woody that it has been an honor serving him; then he wishes them luck. They appear again at the end of the film where they land on Sunnyside, and possibly recognizing Barbie, living a happy life under Ken and Barbie's leadership.
