Panzertruppenschule I (Armoured Troops School No.1) was originally formed as the Kraftfahrkampftruppenschule on 1 October 1937 at Wünsdorf.
The Panzertruppenschule was a 'branch school', where officer candidates were sent after 12–16 weeks spent in basic training, and having successfully undertaken an 8-week course at a Kriegsschule.
Upon graduation, the recruit was promoted to Oberfähnrich and sent on field probation.
In June 1943, the only known flame-throwing versions of the StuG III, designated StuG III (Flamm) were delivered to the school, but were shortly thereafter destroyed by a fire started by a faulty flamethrower.
In late 1943, the school was stripped of its experienced instructors, who were used to form the élite Panzer-Lehr-Division.
