Can you enlist straight into the 37F MOS as Active or Reserve ?

I know this post was made two years ago, however, just to set some things straight. I have a seat reserved for 37F and have already met the pre entrance requirements.

The answer used to be Yes for reserve, No for active. Active duty had to be assessed and selected prior to going through the training pipeline. Now, there is an option for initial entry to complete OSUT as an MP and then move on to be assessed and selected to complete the training pipeline. Talk to your recruiter if you haven't already started the process. Active duty has many more opportunities for career advancement and assignments than reserves. Additionally, active duty 37F only support SOF units (SF, Seals, MARSOC, etc), whereas reserve units mostly support conventional units.

Yes you can if you qualify enlist for that MOS. Go see your nearest recruiter. They can tell you what the requirements are to be awarded the MOS. A Reserve recruiter can even tell you if they see any openings for that MOS in your local area.
