Закавказский фронт
The last major operations of the German-Soviet War which involved substantial numbers of T-26 tanks were the Battle of Stalingrad and the Battle of the Caucasus in 1942. Though the T-26 saw no active action on the main Soviet-German front in 1943, the T-26 still equipped some rearward units. Thus T-26 tanks of the 151st Tank Brigade (the 45th Army, Transcaucasian Front), equipped with 24 T-26s and 19 British Mk VII Tetrarch light tanks, guarded the Soviet-Iranian border. This tank brigade was redeployed to Tuapse (47th Army) in January 1943.
