Sarge, (also known as Army Sarge and Sergeant), is the gung-ho commander of an army of plastic toy soldiers from Bucket 'O' Soldiers, voiced by R. Lee Ermey and loosely based on Ermey's role as Gunnery Sergeant Hartman in Full Metal Jacket. 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." Sarge and his soldiers go on missions to help Andy's toys check up on Andy's activities with his friends or family. Sarge and his troops frequently help out their fellow toys. With their assistance, the toys discover what presents Andy and Molly are getting on birthdays and Christmas.
After Woody’s announcement of Andy’s birthday startles the toys, Woody instructs Sarge to take his troops to report what Andy's presents are. Sarge alerts his soldiers that this is a Recon Plan Charlie, in which the soldiers communicate what Andy receives through a baby monitor. After sending out two paratroopers to scout the area, Sarge leads a group of men down via a jump rope, however, they are forced to freeze after Andy’s mom walks in, injuring a minesweeper. Despite his demands, Sarge carries the injured soldier back to a plant, where Sarge reports back to Andy’s room through the baby monitor. Sarge successfully reports all of Andy’s presents back to Andy’s room, however, right after he tells the soldiers to pack up, he sees Andy’s mom bring out a surprise present from the closet, and instructs them to turn it back on. Due to feedback back in Andy’s room, Rex gets anxious and accidentally knocks the baby monitor off the nightstand, making its batteries to fall out. After Woody puts the batteries back in, all they can hear is Sarge’s warning that Andy is coming upstairs, forcing the toys to scramble back to their places. The surprise present from Andy's mom that Sarge has been unable to identify turns out to be a Buzz Lightyear action figure.
The Bucket O Soldiers, which Sarge and his troops are stored in is now packed up near Andy’s desk for the move. After Woody accidentally knocks Buzz out the window, Sarge, believing that Woody has done this intentionally, harangues him until Woody cuts him off by closing the lid on the bucket. Once the toys begin to get hostile towards Woody, the Bucket O Soldiers bursts open, and Sarge instructs his men to swarm Woody, which encourages the other toys to attack Woody as well. Before anything is done, however, the toys retreat due to Andy approaching.
At the end of the movie, Sarge is proud to work under Woody again for Woody's deeds in helping save Buzz. He is seen leading his troops through another Recon Plan Charlie for Christmas presents (they are hiding in the Christmas tree). He is able to identify Molly's first present as Mrs. Potato Head, but is unable to find out Andy's first present until the toys hear Andy's excited voice saying, "Wow! A puppy!"
In Toy Story 2, Sarge oversees his men searching the toy box for Woody’s missing hat. After Slinky eventually finds it, Sarge orders the Green Army Men, along with Rocky Gibraltar to guard the door from Buster, who eventually overpowers them. Once Andy returns to his room, he has time to play with his toys for a little bit before he leaves for Cowboy Camp. In this scenario, the soldiers are minions of the Evil Dr. Porkchop, who sits perched on the Bucket O Soldiers. He, who has kidnapped Bo Peep forces Woody to choose whether she shall die by Barrel of Monkeys, or Shark. Woody calls upon the help of Buzz Lightyear, who bursts onto the scene riding RC. This knocks the Evil Dr. Porkchop off the Bucket O Soldiers that he’s on, and knocks over the soldiers.
Once the yard sale is announced, Sarge assists Buzz in gathering the toys together for an emergency role call.
In Toy Story 3, Sarge and the rest of the Green Army Men are seen being played with a young Andy in flashbacks. Now that Andy is almost 18-years old, Sarge is only one of three remaining Green Army Men in Andy’s room (the others are the two paratroopers). First, they assists the remainder of Andy’s toys in trying to get them noticed by Andy in Operation Playtime. They bring a phone into the toy chest, while dialing his number on another phone so that Andy has to notice them. The plan fails, as Andy retrieves the phone, but ignores his old toys (he blaims the incident on Molly). After it’s announced that Andy’s preparing to go to college, the Green Army Men plan to leave Andy’s room for good. About to parachute from Andy’s windowsill, they explain that when Andy cleans his room, he and they will get thrown out. Woody tries to reassure them, but they jump out of the window anyways, with Sarge grabbing onto one of the paratrooper.
At the end of the movie, the troops finally land in the playground at Sunnyside Daycare, and Ken and Barbie, now leaders of Sunnyside, walk over to greet them. Sarge salutes to Ken, Ken salutes back to Sarge and the soldiers, and Barbie directs them to the sandbox, inviting them to join the party. That night, Sarge and his two paratroopers are seen standing on the ceiling lights in the Butterfly Room as Sarge directs his paratroopers to lower the disco ball for Bookworm to light it up with his flashlight so the Sunnyside toys can enjoy a disco that is held in the room.
- Sarge is one of the figurines in the Toy Story Collection Bucket O Soldiers. It includes his normal pose, as well as his famous saluting pose. The 2nd very unrealistic version of the set (for some strange reason) has Sarge as a paratrooper.
- Sarge makes an appearance in Toy Story 3: The Video Game.
- Sarge is one of two Pixar characters with the name Sarge.
