Sean Vickers

Vickers is one of two Green Berets that rescued Nate from a cave in the mission Captured.

In-game
He along with Casper was sent in to gather intel about WhiteKnight from Nguyen Trang's base camp. After rescuing Nate from the caves, Vickers briefed Nate on their mission to capture and interrogate the VC officer. Nate accompanied the pair as they attacked Trang's camp. Nate and Casper proceeded to clear an underground tunnel while Vickers sweept the surface. After escaping from an undergound prison, Nate found Vickers mortally wounded in a trench, yelling "Trang!" The Green Beret was shot dead by the officer a few seconds later.
