Miss. Code Ann. § 33-13-23: Miss. Code Ann. § 33-13-23

Any person subject to this code charged with an offense under this code shall be ordered into arrest or confinement as circumstances may require; but when charged with only an offense normally tried by a summary court-martial, such person shall not ordinarily be placed in confinement unless a threat to himself or others. When any person subject to this code is placed in arrest or confinement prior to trial, immediate steps shall be taken to inform him of the specific wrong of which he is accused and to try him or to dismiss the charges and release him. Persons confined other than in a guardhouse, whether before, during or after trial by a military court, shall be confined in civil institutions designated by the Adjutant General.
