A MOS 6510 microprocessor
The change from the 2500 field to the 0600 field has been taking place over the last decade. The only one I can answer for is the migration of the 2542/4066/065x. When I enlisted in 1998 we had 2542 Comm Center Operators. By 2000 the 2542 MOS had been merged with the 4066 Small Computer Systems Specialist MOS. In 2002 the 4066 MOS was split into 2 MOSs 0651 and 0656. The 0651 MOS is the Data Network Specialist while the 0656 is the Tactical Data Network Server Operator. The rest of the 2500 field joined the 0600 field when the 2542s joined the 4066 MOS back in 2000.
It is MOS 1141.
MOS stands for Military Occupational Specialty. You may hear MOS 68F or something else. Each job is assigned a MOS.
Mos Certification = Microsoft Certification
