The 91st Mobile Reconnaissance Corps, also identified as the 91st Mobile Reconnaissance Force, the 91st Expeditionary Corps, or simply as the 91st Recon Corps, was a clone trooper corps in the Grand Army of the Republic. During the Clone Wars, a pan-galactic conflict between the Galactic Republic and Confederacy of Independent Systems, the 91st was placed under the command of Jedi General Adi Gallia and Clone Marshal Commander CC-8826. Throughout the war, Jedi General Mace Windu was also in command of the corps, with Jedi Generals Oppo Rancisis and Stass Allie taking command during the Siege of Saleucami and its aftermath. Following the transformation of the Galactic Republic into the Galactic Empire and the commencement of the Great Jedi Purge, the 91st Mobile Reconnaissance Corps was reorganized under the new Imperial Army.
