Would a recruiter send a prior service to MEPS a second time?

There would be no need to go back to MEPS. The recruiter would be able to determine if MEPS had other offers available. The military fills priority first, and since this young man was a former 13B the government would save money I trainjng. Truthfully, the military also looks at re-entry as kind of a gotcha, which if you think about it makes sense. If you quit your job for greener pastures and later went back to your former employer because things didn’t work out the former employer is not likely to offer you anything other than what they have available. The real question is how motivated is this young man regarding serving his country again. It is not just a job! He can either be patientvor take what they offer. Keep in mind that when there are is a surplus in potential new recruits the military does not keep the window open for re-entry.

Yes they can always turn down the jobs and return later. As prior service you're very, very limited. You need the Army more than they need you, and your bargaining leverage is very limited. On top of that, there's no guarantee the job you want is going to be there next month.

The recruiter had zero control over the MOS’s offered at MEPS. Nobody knows what MOS’s will be offered by the Departmebt if the Army until said applicant is at MEPS ( PS specific)

You can turn down anything but remember you can only get jobs you qualify for... so retake the ASVAB

They can but as a prior service even more than a first timer, is a bout needs of the Army; and the 1st option is whatever the prospect is already trained. Other than that the Army publishes a list of potential options for prior service folks. It’s called Business Rules, and again, is all about what the Army needs at that particular moment .
