(a) The Kansas military board is hereby empowered and directed to erect or provide, anywhere within the limits of this state, upon such terms and conditions as shall be decided upon by the Kansas military board as most advantageous to the state, armories for the use of the Kansas army or air national guard. Each such armory shall be used for drill, meeting and rendezvous purposes by the unit of the national guard occupying such armory, and such other public functions which the officers in charge of such armory may deem advisable and proper. Such armories shall also be opened for meetings and functions of the Grand Army of the Republic, the Spanish-American War Veterans and their auxiliary organizations.

(b) Subject to the provisions of Kan. Stat. Ann. §§ 48-324 and amendments thereto, the adjutant general, with the advice of the Kansas military board, shall adopt rules and regulations establishing a uniform policy governing rental charges for use of armories for other than national guard purposes in order to recover the costs incurred for such use.
