Alex "Tig" Trager (Kim Coates) is a member of SAMCRO, a veteran of the U.S. Marine Corps and was previously sergeant-at-arms under Clay's rule but gave up his sergeant-at-arms patch in Season 4. He is particularly loyal to Clay and is one of the club's more violent members, who has on occasion mentioned disturbing parts of his past, including his mention (perhaps jokingly) of enjoying necrophilia and bestiality. Though respecting Jax's intelligence, Tig questions Jax's ability to lead as SOA enters a more brutal era in the club's history with the Mayans and the Nords. Tig was the one who was to carry out the hit on Opie but instead mistakenly killed Opie's wife, Donna. Afterwards, Tig seemed to be in a state of depression and fought with Jax after Jax forced him at gun point not to kill the witness who was going to identify Bobby and Opie for the murder of Brenan Hefner. He also allowed Opie to beat him after confessing to Donna's accidental murder.
