Re: Commander Approval for OCS
See above. If a SM enlists with the 09S MOS, they are guaranteed a slot in the OCS program. Whether thier temporary commander approves or not is irrelevant b/c once they start Phase 1, they are reassigned to the OCS unit under control of the Company Co there. They'll stay on the books of the old unit but this is mainly to do with them having thier TA50 issued out, etc.
Now, whether or not they pass the course is completely up to the individual...
