Unlike the Enrolled Missouri Militia it was a full-time force.
Reliable Unionists were selected from the EMM regiments and the enrolled militia were disbanded.
The new provisional regiments were paid by the state, but were outfitted and supplied by the Federal government.
Primarily they opposed guerrillas and served as local garrisons.
[1] Like the Missouri State Militia Cavalry the PEMM soldiers would be eligible for federal pensions.
