In almost every army in the World, the Military Police rank amongst those who are least liked by other soldiers despite the essential duties that they carry out, often being amongst the first in and last out in any theatre of war. In the German armed forces, however, opinions of the military police were often those of fear as much as dislike, so great were the powers held by these troops. Germany created a plethora of different branches of what were termed 'Ordnungstruppe' - Troops for Maintaining Order. Many wore a distinctive metal gorget plate on a chain around the neck, leading to their pejorative nickname 'Kettenhund' or Chain Dogs. Despite certainly being involved in often brutal treatment of partisans and other unfortunates who fell into their grasp, their skills were sufficiently appreciated by the allies that on Germany's surrender, a number of military police units of the Wehrmacht were allowed to remain in post under allied control to assist in controlling the vast number of now disarmed German troops. Kettenhund!The German Military Police in the Second World War, using primarily previously unpublished photographic material from private sources, provides a detailed study of the organisation of these units and the distinctive uniforms and insignia they wore.
