What information or advice do you have for a 15R looking to reclassify to 88K?

Have a couple of MOS's you're willing to accept, 99% chance there will not be a class seat for 88K when you ask for it

Are you reclassing as part of a reenlistment contract or are you hoping to do it before that? If prior, check out the latest In/Out calls* (I already looked - 15R isn't listed as an over strength MOS and 88K isn't listed as a shortage MOS)

Without knowing what type of information or tips you're looking for (process to go about? what's the MOS like? etc.), it's a bit hard to give you anything.

However, you might want to check the following similar threads on RP that might have some of the questions addressed:
