The Sentinel Commander is a character from Terror in New York City. He ordered missiles to be fired at Thunderbird 2 because he believed it posed a threat.

Having put Thunderbird 2 out of action he was ordered by Washington to take Thunderbird 4 to New York when it was needed in a rescue mission. Placing Thunderbird 4 onto the deck he made the trip to New York Harbour via the Panama Canal in 22 hours.
