Commander Kessler (ケスラー司令官, Kesurā-shireikan) (named Grant Kessler through means unknown) is the commander-in-chief of the Special Tactical Force and Special Task Force. Kessler received positive verification from a distress call when the U.R.D.A. occupied Garland Square without warning, demands, or any motivation. Sensing suspicion within the URDA's reasons to take over Garland Square, Kessler dispatches S.T.F.'s ace squad—Platoon One (led by Claude McGarren) to do away with the U.R.D.A.. Later, realizing that his daughter, Melissa, was kidnapped by the U.R.D.A., he resends Platoon One to do away with the remnants at Grassmarket Steet and the Belforte Hotel hoping that Platoon One will secure his daughter to safety.
