A 79-year-old U.S. Army veteran fought off a would-be robber at an Orlando 7-Eleven gas station, authorities said.

The confrontation was caught on surveillance camera on Saturday morning.

Orange County Sheriff's deputies said Marvin Lail was filling up his car when a man came from behind the gas pump and demanded his wallet. But Lail fought back, even after the man pulled out a gun.

Lail believes the man targeted him because of his age, saying, "Give it up, old man."

Lail said the man would have had to kill him to get the wallet.

Eventually, a gas station employee intervened and the would-be robber fled before deputies arrived.

Deputies are searching for the man.
