In January 1944 as the Red Army began to advance on the Eastern Front, the power of the "Feldgendarmerie" was superseded by the creation of the "Feldjägerkorps". Answering only to the German High Command (OKW), its three regiments were founded to maintain discipline and military cohesion in all branches of the "Wehrmacht" (including the "Feldgendarmerie"). Feldjägers were recruited from decorated, battle-hardened officers and NCOs. They had the military authority of the OKW to arrest and execute officers and soldiers from either the "Wehrmacht" or the SS for desertion, defeatism and other duty violations. Every unit of the "Feldjäger" had command of a "Fliegendes Standgericht" (flying drumhead trial/flying court martial), which comprised three judges.
