GENTEXT/REMARKS/1.  This MARADMIN authorizes qualified active Marine Corps Law Enforcement (LE) professionals who possess valid Law Enforcement Officer Safety Act (LEOSA) 18 U.S.C. §926B credentials to carry concealed privately owned firearms (POF) aboard Marine Corps property in the United States and U.S. territories for personal protection not in the performance of official duties.
2.  In December 2019, the Department of the Navy (DON) suffered two fatal active shooter incidents aboard Naval Base Hawaii and Naval Air Station Pensacola.  These tragic events prompted Headquarters Marine Corps (HQMC) to accelerate existing efforts to develop concealed carry policies aligned with SECNAVINST 5500.37, “Arming and the Use of Force."
3.  SECNAVINST 5500.37 authorizes the Commandant of the Marine Corps (CMC) to grant permission to Marine Corps uniformed and civilian personnel to carry a POF aboard Marine Corps property for personal protection not in the performance of official duties or status.  Through this MARADMIN, the CMC authorizes only Marine Corps LE professionals who possess valid LEOSA 18 U.S.C. §926B credentials to carry a concealed POF aboard Marine Corps property.  Marine Corps property are Marine Corps installations, bases, and stations in which the Marine Corps exercises primacy for LE functions.
4.  MCO 5580.4, “Implementation of the Amended LEOSA,” with changes captured in MARADMIN 470/18 and AMHS message DTG 231907Z Aug 18, codifies requirements for the concealed carry of a POF by Marine Corps LE professionals for personal protection not in the performance of official duties.  Per MCO 5580.4, Marine Corps LE professionals are defined as Military Police, Criminal Investigators, and Marine Corps Law Enforcement Program Police Officers who meet credentialing requirements for concealed carry of a POF for personal protection. 
5.  This MARADMIN authorizes Marine Corps LE professionals, who maintain LEOSA 926B credentials, to carry a concealed POF aboard Marine Corps property while off-duty.  The authority of this MARADMIN does not extend to Marine Corps LE professionals on joint bases, on other Department of Defense (DOD) property under the cognizance of another DOD service, or on other federal facilities.  This MARADMIN does not authorize other DOD LE professionals to carry a concealed POF on Marine Corps property.
6.  Marine Corps LE professionals must comply with concealed carry requirements as set forth in DODD 5210.56, “Arming and the Use of Force.”  Restrictions and special considerations, including POF registration, POF storage and transportation, and adherence to POF concealed carry policy, as prescribed in MCO 5580.4, remain in effect.  Pursuant to 18 U.S.C. §930(d) and DODD 5210.56, Marine Corps LE professionals are authorized to carry a concealed POF for personal protection not related to the performance of official duties within buildings and facilities located on Marine Corps property except for DOD schools in accordance with 18 U.S.C. §922(q), “Federal Gun-Free School Zone Act of 1995,” courtrooms unless previously authorized by the military judge, or where otherwise prohibited by law. 
7.  HQMC will continue to develop policy to address the total force  requirements for the carry, transport, and storage of concealed POFs aboard Marine Corps property aligned with SECNAVINST 5500.37.  Installation commanders and arming authorities charged with implementing the provisions of this MARADMIN should consult their servicing Staff Judge Advocate to ensure local policies comply with law, regulations, and policies.
