Coral Snake

Coral Snake was a secretly funded NSA team led by Jonathan Wallace. It was used by Roger Stanton during Day 2 to try and sneak the nuclear weapon into the country. They had previously recruited Jack Bauer and all of its members have a snake tattooed on their right arm.

Day 2
Coral Snake first arrived on the scene when they blew up the plane that was carrying Jack Bauer and Nina Myers. They were able to fight them off, but Jack spotted their tattoo on one of the commandos and reported it to David Palmer.

Later in the day, they were intended to stop the nuclear weapon that was coming into Los Angeles, but their captain, Wallace, turned on them after he was paid off by Peter Kingsley.
