Aloysius "Tector" Murphy was a fighter in the 2nd Massachusetts Militia Regiment. Although a member of the sub-group Berserkers, he is fiercely loyal to the 2nd Mass and a brilliant marksman. Tector informs Weaver he hides his rank (former USMC gunnery sergeant) because he blames himself for losing his squad in an ambush.
In Season 4, during the Espheni assault on Chinatown, Tector is recruited by Tom Mason, being the best shot to help put an end to the battle and kill Scorch, the commanding Overlord wanting revenge on Tom. Tector tells Tom to get him oil for the gun, and after he leaves, Tector begins to line up the shot, wearing the ghost mask to disguise himself as Tom. Tector shoots, penetrating his armor only. Scorch sends down a beamer on his location, and after sends a skitter to confirm his death. Tector takes his mask off, says "Tick Tick Boom" and blows himself up with C4 charges. Scorch confirms the "Tom's" death and calls him forces away from Chinatown.
