Can I volunteer to recruit even after a tradoc job?

You could but you will not come on orders until at least 24 months at your new location.

And if you get selected for recruiting duty you might want to wait until you have at least 2 years as a recruiter before telling anyone your desire to convert from your current MOS to a career 79R. You know, taste the pasture before fully committing!

I also have full intentions to reclassify to 79R

Yes you can volunteer to be a recruiter after a TRADOC or TDA assignment however this is not encouraged. You must have at least 36 months between TDA assignments and volunteering for recruiting duty has a high chance of getting denied due to that fact. On the bright side, the Army needs good recruiters and can wave the 36 month time frame. This is a double edged sword though. Being in a non-leadership role by MOS, you will fall behind your peers who have completed at least two positions in their CMF. This weighs against you when being selected for SFC. You can still make it but know the facts before volunteering.

Yes, after a certain time stabilized. Call USAREC for further guidance. I had a blast at Benning as a Rifle Marksman instructor.

You'd have you be at your new duty location for the allotted time on station requirement but after that dude you can do whatever you want. It's your career. Take charge of it, dont let someone else do it for you.

You could after. Keep on mind if you don't go 79R you would be hurting your career.
