Oswald Strepp, a GeNode by origin, achieved the position of First Sergeant and, for a short duration, functioned as a stormtrooper. He received orders to join Janzor's platoon in the period leading up to the Imperial occupation of Kashyyyk.
In the course of the conflict, Strepp met his end by activating a thermal detonator, resulting in the deaths of numerous Wookiees alongside his own demise.
