The roots of military police in the Lagerburg Army can be traced back to the Reitendes Feldjagerkorps (RFJK) of Friedrich II. Upon accession to the newly-created Duchy, Albrecht borrowed from the Prussian model to create his own police and security force. In contrast to the Prussian regiment, however, the Lagerburg RFJK was trained and employed for civil law enforcement duties as well.
The Duke made use of the most recent advances in the sciences and law in order to create a model organization. He established an academy in Felsenfall for the training of recruits; basic literacy, physical fitness and prior education were prerequisites for admission. As indicated by the nature of training, a heavy emphasis was placed on law enforcement and criminal justice. Subjects taught in the RFJK academy were:
Criminal police methods
General & special police powers
Criminal, forestry, fishery, industrial and waterway codes
Passport and identification duties
Weapons drill & marksmanship
Scouting & reporting duties
(It may be noted that much of the training would eventually be brought together to create an Olympic sporting event, the Pentathlon.) The rank structure reflected the mainly police duties of the organization. The commander of the force held dual titles of Chief Magistrate and Colonel, each used when appropriate. In peacetime the duties of the Reitendes FeldJagerKorps (RFJK) were to enforce and administer civil law; during general emergencies troopers were tasked to conduct reconnaissance, control military traffic, carry important messages, and protect members of the ducal family.
As members of the RFJK rose through the ranks, their roles and assignments likewise changed. In peacetime, rank and file troopers were employed as police officers or constables assigned to towns and cities in the Duchy, and officers held positions as circuit judges. When the Duchy went to war, the RFJK would muster at Felsenfall to be organized as the senior regiment of light cavalry. Later a battalion of Feldjagerkorps zu Fuss, was raised to supplement the RFJK.
