Active Duty Military and 'assault weapons'
In 2011, the MAWP program was altered to require the signature of one's base/post commander verifying that the weapon is required for duty use. That requirement has, in practice, killed the program.
Active duty military with PCS (permanent change of station) orders to California and who own personal weapons California defines as 'assault weapons' should contact the California Department of Justice regarding a Military Assault Weapon Permit (MAWP). CA-DOJ also suggests you contact your base/station/post legal staff for assistance.
With a MAWP, the service member may bring those weapons on the permit into California.
Once obtained, the MAWP may be renewed annually. If the service member separates from Active Duty while in California, the MAWP is no longer effective, and the 'assault weapons' become illegal and must be removed from the state or otherwise handled according to law.
