Squad Klaus (クラース班 Kurāsu-han?) was a squad within the Scout Regiment led by Team Leader Klaus. It was composed of many new recruits and was one of the central teams partaking in the operation to recover Shiganshina District where they safeguard the horses.
Klaus Squad participates in battle and remains by the interior side of Wall Maria while the other soldiers head to the outer gate. After the appearance of the Beast Titan the squad is reinforced by Dirk Squad and Marlene Squad with orders from Erwin Smith to protect the horses from Titans.
As the soldiers begin to slay the incoming Titans, they are crushed by projectiles from the Beast Titan, leaving only a portion of the squad alive, consisting of the fresh recruits. They retreat with Levi and head towards the Walls with the horses they have been ordered to guard. The remnants of the squad are later given orders by Erwin to act as a decoy while Captain Levi uses the diversion to assassinate the Beast Titan. This is done through a mounted suicide attack using signal flares to throw off the Beast Titan's aim. The entire squad is killed in the charge with the exception of Floch.
