From 1934, every division of the German Army had a court martial. After the occupation of Poland, the "Oberkommando des Heeres" wished to introduce a system which allowed speedy trials to be performed, as it was believed that a fast process would be a more effective deterrent. In November 1939 a law was passed which permitted drumhead trials if it was deemed necessary during warfare. Every commander of a regiment could either decide to inform the court martial of his division or he could convene a drumhead trial when somebody was accused of a crime. The decision of a drumhead trial could be executed immediately. With the beginning of the year 1944 the high command formed a special police, the "High command "Feldjäger"", which were in command of special drumhead trials named "fliegende Standgerichte", composed of motorized judges.
