SO - Special Operations (Navy SEAL) - Contracts

SO - Special Operations (Navy SEAL) - Contracts

My son Owen who is 17 and a senior is talking to a Navy recruiter regarding DEP. Owen has taken the ASVAB, and our understanding is he scored an overall 85%. Owens primary interest is SO - Special Operations (Navy SEAL). With a secondary rate of HM if he cannot qualify for the SO rate. The recruiter is telling him that assuming he passes his MEPS physical, and the required scores on the ASVAB are meet, that if offered, he would not be able to select SO as a primary selection in his contract, but that it would rather be a secondary selection which he would have to request while in basic training. Is this correct?

It will be in his contract that he is requesting that rate right?

According to usmilitary.about.com he would sign a contract to enlist in the DEP program, and again before he goes to basic. The recruiter is telling him that he would sign a third contract before he begins SEAL Training Challenge if selected. Is this correct?

In what contract would he need to make sure that he has requested SO, and any verbiage regarding any enlistment bonuses which have been promised, in the DEP contract, or the active duty contract? Or neither as it would be specified in a specific SEAL Training contract? 

The recruiter has also promised a 30k bonus if he does the SEAL Training Challenge?

Is there no way he will be offered the SO - Special Operations (Navy SEAL) rate even if he qualifies during MEPS?

Thanks for your replies
