The Epirus Army Section (Greek: Τμήμα Στρατιάς Ηπείρου, ΤΣΗ; Tmima Stratias Ipeirou, TSI) was a field army of the Hellenic Army active between 14 February and 20 April 1941 during the Greco-Italian War and the Battle of Greece.
The Epirus Army Section was established on 14 February 1941, with the I Army Corps and II Army Corps fighting on the western and central sections of the Albanian front. Until that point, the two corps had been under the direct control of the General Field Headquarters at Ioannina, led by the Greek commander-in-chief Lt. General Alexandros Papagos. However, the increasing possibility of a German attack through Bulgaria necessitated the relocation of GHQ back to Athens and the establishment of a new higher command. The first commander of the Epirus Army Section was Lt. General Markos Drakos, who until then had commanded the Eastern Macedonia Army Section.
After vehement disagreements with GHQ on the future course of operations, on 6 March Drakos was retired along with his two corps commanders, Lt. Generals Panagiotis Demestichas (I Corps) and Dimitrios Papadopoulos (II Corps). Markos was replaced by the commander of the Western Macedonia Army Section, Lt. General Ioannis Pitsikas. I Corps went to V Corps commander Lt. General Panagiotis Demestichas and II Corps to 3rd Infantry Division commander Major General Georgios Bakos.
