NC trooper cadets at the academy in Raleigh and KY trooper cadets in Frankfort are frequently reminded they have a familial connection to the PSP through their training process history. The PSP was patterned after a military organization and PSP troopers have sometimes been referred to as "Soldiers of the Law and Order". Divisions of the force are called "troops", and officers are known as "troopers", a title usually reserved for members of the United States Cavalry, and reminiscent of the early beginnings of the department when officers patrolled on horseback. Regional headquarters, at which single troopers were once required to live, are referred to as "barracks". The original concept was that the troopers did not apply to join the PSP but "enlisted" for two-year periods, after which they could be honorably discharged or apply for reenlistment.

After 1927, troopers were allowed to marry after they had completed their first two-year enlistment if they had approval from the police superintendent. The PSP allowed married men to enlist in 1963.
