MOS 1321 is a new primary MOS established by MARADMIN 235/26 (27 May 2026) and effective 1 October 2026 under the FY27 MOS Manual. It merges Metal Worker (1316) and Machinist (2161) into a single multifunctional specialty that fills the Marine Corps need for formally trained advanced manufacturing specialists, with a training pipeline that adds 3D printing and hybrid additive and subtractive systems to traditional welding and machining. Fabrication specialists produce replacement parts at the unit level, including in remote or austere environments where conventional supply chains are limited. Marines in both parent specialties will be recoded to 1321: prior Machinists complete Fabricator A (Welding) and prior Metal Workers complete Fabricator B (Machinist) at the formal school at Fort Lee, with a suspense of 1 October 2030. The active duty field will number roughly 390 Marines, and the merger also consolidates promotion competition so fabrication specialists compete exclusively against their peers.","A Fabrication Specialist manufactures, repairs, and modifies components using 3D printing, machining, and welding, combining the former Metal Worker and Machinist specialties.
