His real name is Tormod S. Skoog, and his rank is that of specialist E-4. Tripwire was born in Hibbing, Minnesota.
Because his father was a career naval officer, Tripwire went to high school in Yokosuka, Japan. However, he dropped out to spend two years in a zen monastery, pondering the meaning of life. He was evicted for multiple accidents due to his clumsiness. Tripwire joined the army at age 19, and claims to have received spiritual awakening on the grenade range. He is proficient with all NATO and Warsaw Pact explosives, detonators, ignition initiators and blasting machines, and is a qualified expert with the M1911A1 Auto Pistol.
