You will fix other people's pay problems while your own pay is somehow also wrong. Service record books have errors dating back to before you were born and it will become your personal mission to correct them all. Every Marine in your unit will treat your desk like an emergency room, showing up two days before the deadline for an action that needed a week. The HR and personnel administration skills are genuinely transferable — payroll processing, benefits administration, and records management are civilian jobs that exist everywhere. SHRM certification after separation gives your military personnel experience civilian structure that hiring managers recognize.

You maintain howitzers. The M777 is an impressive piece of engineering — titanium and aluminum, 9,800 pounds, can drop a round within meters at 30 kilometers — and you are responsible for keeping it that way. The work is mechanical, precise, and occasionally done in field conditions that the maintenance manual did not anticipate. With the Marine Corps cutting from 21 cannon batteries to 5 under Force Design 2030, the 2131 community is small and getting smaller. The remaining billets are high-demand because the guns that are left need to work perfectly every time. Heavy equipment maintenance and machinist skills transfer to civilian manufacturing and defense maintenance contracting.
