I grabbed this off of this site:
http://www.templarhistory.com/hierarchy.html
Based on the Knights Templar, it gives an excellent framework for the hierarchy for militant churches.
The Templar Hierarchy
The Grand Master: Absolute ruler over the order answered only to the Papacy
Seneschal: Acted as both deputy and advisor to the Grand Master
Commander of the Kingdom of Jerusalem: Was in charge of The area and had same powers as Grand Master within his own jurisdiction
Commander of the City of Jerusalem: Was in charge of the area and had same powers as Grand Master within his own jurisdiction
Commander of Tripoli and Antioch: Was in charge of the area and had same powers as Grand Master within his own jurisdiction
Drapier: The Drapier was in charge of the Templar Garments
Commander of Houses: Acted as lieutenants to higher authorities within the order but carried little actual power themselves
Commander of Knights: Like the Commander of houses, acted as lieutenants to higher authorities within the order. They carried little actual power themselves
Knight Brothers: These were the warriors who wore the white tunic and cross. Each was equipped with three horses and armaments
Turcoplier: The purpose of the Turcolier was to command the brother sergeants in battle. The Turcopolier would lead the march along with a guard of knights
Under Marshal: The Under marshal was in charge of the footmen and the equipment
Standard Bearer: The Standard Bearer was one of the sergeants and charged with carrying the order's banner
Sergeant Brothers: These warriors were support troops and did not have to be nobly born. Although similarly equipped to a full knight, the sergeants had one horse and no squires under them
Turcopoles: These were the local troops who would fight along side the Templars. Similar to the sergeants
Sick and Elderly Brothers: No longer active members but still members of the order
