As the 6th Panzer Division, it participated in the 1940 Battle of France. The Division contained a single Panzer Regiment, the "Panzer-Regiment 11", which in turn contained three abteilungen, or battalions. The 11th Regiment was equipped with 75 Czech-built Panzer 35(t) tanks which proved efficient but difficult to maintain because the maintenance manuals were in Czech rather than German, and spare parts were less readily supplied and harder to easily requisition as a result. Furthermore, there were 6 "Befehlspanzer 35(t)", which were a subtype of the 35(t) designed for military commanders, as well as 45 Panzer II and 27 Panzer IV.
