William Dunbar, of Berlin, Pa., was on duty at the Army National Guard Training Center when he said, "If someone pays me enough money, I will kill the vice president," Richland County cops said.
Witnesses said they alerted commanding officers after they heard Dunbar make the threat twice on Saturday.
He was charged with disorderly conduct and making terroristic threats, both misdemeanors.
Dunbar was taken to Conemaugh Memorial Medical Center for evaluation and then to county prison, where he was held on $250,000 bond, officials said.
