Senior Chief Petty Officer Wolf Taylor is a member of the Royal Australian Navy who joined the team along with Ravit Bivas aboard the USS Nathan James under the command of Commander Tom Chandler after the ship landed in Norfolk, Virginia.
Taylor joined the Royal Australian Navy and became a diver, E.O.D. expert, and all around operator. SCPO Taylor was a member of the USN's Navy Special Warfare joint operation Training program in Norfolk. He at some point befriended Lt. Ravit Bivas and they were close enough for him to call her a "sister." Therefore he can be considered both professional and platonic.
Wolf and Val are shown flirting frequently during Season 2 and the first episode of Season 3, but their relationship is cut short when Val dies at the end of Season 3, Episode 1.
During Seasons 4 and 5, Wolf and Azima Kandie develop a romantic relationship.
During Season 5, Wolf is grievously injured by a landmine while on a mission in Panama. In "Warriors," several months later, he is shown to have recovered, but with a scar traveling all the way from ankle to mid-thigh.
