How does it work to reclassify from 11C to 68W?

You have to be on station one year before you can request a voluntary Reclass. You can only voluntary Reclass if your MOS is balanced or over strength and you're moving into a more under strength MOS. Right now your MOS is balanced and 68W is understrength.
The second way is that once you're in your reenlistment window you can request to reclass. HRC will decide based on the strengths of each MOS. The only way to reclass is through your career counselor. Please don't bring any Reclass 4187s to your S1.
If you wanted to be an 11B still you will need a memorandum from Infantry branch accepting you, or a Ranger tab. It's still processed the same way.

Well if medical is what you know you want, and you know it’s overstrength, I would speak to a Civil affairs recruiter. They have a 38BW4 which is a Civil Affairs Medical Sgt. You go through CA Assessment and selection, airborne school, MOS training, language training, and the first half of Special Operations Medical (SOC-M) school with Rangers, SARCs, SOAR, etc. where upon completion, you will assume the medic role in your CA team.

With a school like that under your belt and Airborne it should be a breeze becoming 68W proper. My buddy left 74D and became 38BW4 and went from zero deployments to three 4-6 month long deployments. Sometimes there is no shortcut, but the road less travelled is totally worth it.

Nevermind!
