Staff Sergeant Edgar Jensen (COG tags CSID T9FJ59-44GHG-EL) was a Gear who served in the Clayvale Armed Forces as part of the Confederation of Ordered Government. Originally a Gear in the reformed COG's Army, he deserted shortly after the Clayvale Rebellion began and sided with the rebels, helping fight the COG's new robotic army. During this, he proved himself to be a competent soldier and was quickly promoted to the rank of Corporal, being made second-in-command of Gamma-Six Forty One after the rebelling forces were reorganized into the Clayvale Armed Forces.
Over the next decade, he would continue to prove himself a loyal and valuable soldier, reaching the rank of Staff Sergeant in 40 A.E., and taking a leading role in his platoon. Jensen was present when Confederation first encountered the Swarm in 42 A.E., helping defend civilians in the town of Frallin.
