The election of officers is held in the fall of the year. The treasurer is appointed by the captain, with the approval of the board of directors. The governing body of the Hashknife Sheriff's Posse is the board of directors. The board consists of eight members elected for alternate terms, and a chairman who is elected by members of the board. The past captain serves on the board for one year, and the present captain is an ex-officio member who, along with the treasurer, can vote to break ties.
Most men are willing to work when called on.
The men all take the oath of a deputy sheriff of Navajo County, but are only deputy sheriffs when on call. The sheriff has the authority to call them out and he directs them when called out in service. Both the sheriff and the undersheriff are members of the posse. When on duty, the men are expected to furnish their own firearms, horses, saddles and other equipment necessary for the performance for their duty. To become a member, a person must be sponsored by a member of the posse and be a legal resident of Navajo County.
