He took the rank of Sgt. Slaughter when debutting in Madison Square Garden for the WWWF, and he was instantly hated by the New York crowd for his militant viewpoints. He feuded with top fan favorites like Pat Patterson and Bob Backlund, but then he had a match following The Iron Sheik on WWF SuperStars of Wrestling and history changed course. Sgt. Slaughter took offense to the pro-Iranian comments spewing in the microphone, and upon the arrival of "The Sarge," the fans immediately respected his position and chanted "USA! USA!" repeatedly while Slaughter forcibly removed Sheik from the ring.
His pro-American patriotism garnered the interest of G.I. Joe, which licensed a toy character for him, and he temporarily left the wrestling rings to lend his voice to the G.I. Joe cartoon series.
Upon his return to the ring, Sgt. Slaughter found himself back where his career began, under the watchful eye of Verne Gagne in AWA. Before Slaughter could win the AWA World Championship for America, the WWF lured him back to New York. It was the outset of Operation: Desert Storm, but Slaughter shocked the wrestling world by declaring himself an Iraqi sympathizer. Despite the unpopular point of view, Slaughter was successful in the ring, winning the WWF World title from The Ultimate Warrior at the 1991 Royal Rumble. His championship reign was short-lived, and he lost the title to Hulk Hogan at WrestleMania VII.
Sergeant Slaughter was not finished with Hulk Hogan and he formed the Triange of Terror with General Adnan and Colonel Mustafa (aka Iron Sheik), but their unity could overcome Hulkamania. They faced Hogan & Warrior at SummerSlam '91 in "A Match Made in Hell" (to balance "A Match Made In Heaven". After his failed attempts to reclaim his title, Slaughter opted to reclaim his country, turning on Adnan and Mustafa.
After his in-ring career ended, Slaughter often joined Pat Patterson & Gerald Brisco as one of the Stooges for Vince McMahon on Monday Night Raw during the Monday Night Wars. Fittingly, The Sarge was on the winning side of that war too.
Sgt. Slaughter was a true inspiration to Chris Hughes, who entered the Army to follow his example and he was proud to reach the rank of sergeant himself because that's what rank Sgt. Slaughter was.
