"Sorry gentlemen, this whole area is closed for weapons testing for the next 24 hours. That includes all on-base personnel."―Sergeant Wycroft[src]
By 1957, Wycroft had been based in the desert for five years. One day that year, when the base went on 24-hour lockdown due to nearby weapons testing, Sergeant Wycroft, who hated the desert, was left in charge of four men, including Corporal Higgins and Private Mitchell, at the front gate to keep out unauthorized personnel. Watching a 1932 Ford roadster race against the lead car of an Army convoy, Wycroft bet on the roadster, while Higgins bet on the Army vehicle. Knowing the roadster's engine, Wycroft won the bet and collected Higgins' money.
As the Army convoy arrived at the gates, Wycroft and the other MPs left the guard station to approach the front car. Leaning in to the passenger side of the lead car, he let the guests know about the lockdown. After one of his men saluted "Colonel Truman", walking from another vehicle, Wycroft began to repeat the orders regarding the base closure. However it turned out the "Truman" and all of his men were a group of Soviet Special Forces in disguise. They gunned down Wycroft and his men, and dragged their bodies away from the guard house.
Behind the scenesEdit
Jimmy Wycroft was played by Robert Baker in Indiana Jones and the Kingdom of the Crystal Skull. The character was identified as the "MP Sergeant" in the film's credits. The "Air Police" armband identifies him and his men as members of the US Air Force's Air Police.
While unnamed in the film itself, Wycroft's character is named in the Crystal Skull novelization. In the film's comic adaptation, Wycroft and the other MPs wear different uniforms and round helmets, perhaps similar to Army MP uniforms instead of the Air Force's Air Police uniforms.
