For a while ( may be the same) the Army was using 18x Recruit for special forces contracts. Most washed out and were placed into traditional infantry units. There were a few that were other MOS's but the irony was if they went Infantry they would still have the same options. I think selling someone that they're a SF recruit / SEAL recruit is easier option. For the Navy it makes more sense they are needs of the navy, there really isn't an Infantry outside of the Marine Corps which would be a whole other paperwork issue.
