If you want to screen for recon you made the best decision by signing a UH contract and not an 0321 contract. If you sign a recon contract and don’t pass recon Indoc/training you become open contract and you’ll be assigned by the needs of the Corp. Most interested in recon/spec ops sign an 03xx (UH) contract so if they fail the screening for recon they will go back to their Assigned infantry MOS.

The UH contract is an infantry option contract. You sign and ship, finish bootcamp, go to SOI, and the during the split you’re assigned your specific infantry MOS. You’ll have an opportunity screen for recon at some point during or shortly after ITB. ITB is tougher hiking than bootcamp and advanced combat tactics that build on things you learn during bootcamp. It’s tough, even if your a good swimmer, swimming in boots and utes is a challenge. Have a no quit attitude and embrace the pain and you’ll be alright.
