Task: Question Answering
Input (English): Passage: World War II has ended and Major Larry Briggs finds out that his friend Captain Mike Perry has only two months to live due to a head injury. Larry and Sergeant Pete Rocco are determined to show Mike a good time before he dies. For a $10,000 fee, Larry takes a flying job working for Alex Maris, a profiteer. Everything is set until Maris' secretary, Susan Cleaver, shows up to board the aircraft. Mike falls for Susan and Larry convinces her to play along but she has fallen in love with Larry.
The first flight is disrupted by Maris arriving a half-hour late with the police right behind. Larry takes off but is forced to make an emergency landing after both engines fail. After checking into a small hotel, the Americans find Police Lieutenant Keon, who is shadowing them, believing that they are smugglers.
When Larry sees Mike falling for Susan, he wants the romance to end and despite her carrying $500,000 for Maris, Larry tells her to leave immediately. When Mike longs for Susan, Larry relents and blackmails her into seeing him or he will turn her into Keon. Sailing to Saigon on a boat, Larry tricks Keon by stowing the money away into an envelope he mails to himself, and throws all suspicion off Susan.
In reaching Saigon, Larry knows he has fallen in love with Susan even though Mike has proposed to her. At Susan's hotel, an enraged Maris and his valet Simon, hold Larry hostage, demanding the money that has been posted. Bursting in, Pete realizes what is happening, and fights with Simon, but both men fall off a balcony to their deaths. Susan has secretly arranged to retrieve the money from the post office, returning it to Maris. Mike and Larry confront him but in an exchange of gunfire, Mike and Maris are killed. After Mike's funeral, Larry and Susan start a new life together. 
Question: What rank was the man who fell off the balcony in Susan's hotel?
Output (English): Sergeant.
