Whoop, were you a pilot? I think I may have roomed with you in Pensacola for a bit if I am remembering your handle correctly. Either PM me or shoot me an email out of the global if you want more info than I provided below.
The reserves was working on offering a few training courses you can take to acrue a few points out of the IRR via online classes but I am not sure if that ever was implemented. If you attend a muster you can get a few points. Your likelihood of being able to acrue enough points out of the IRR for a satisfactory year is extremely low if you aren't willing to do any period of duty such as drills, RCT or ADOS.
If you wouldn't mind affiliating with an SMCR unit after you have your masters done and would be interested in a reserve retirement then what I would highly recommend calling Marine Corps Individual Reserve Support Activity (MCIRSA) in New Orleans and talking to them about joining whats called an IMA detachment as a stop gap.
Basically, this option provides you much more flexibility on when you drill or perform short term periods of duty such as RCT and ADOS in order to obtain sat year. You typically won't be required to drill every month, but can achieve a sat year by just doing one or two extended periods of duty throughout the year.
The catch is, MarForRes typically tries to limit you to an IMA Det for only a couple years and then will ask you to affiliate with an SMCR unit. If you are just looking for a transition year or two and would be willing to traditionally drill after you are done with your masters, then this could be a great option for you.
Also, if you are who i am thinking of and you are a pilot, then there is a lot more flexibility for when many squadrons "drill" so you might not have to do the one weekend a month thing to get a sat year with an aviation squadron like you may think.
The best thing to do to see what is available for pilots in the SMCR is to contact a prior service recruiter. Texas' PSR office is located at 8th MCD out of Ft Worth. Once you find a unit you are considering joining, just call the unit direct and talk to the leadership and a few of the pilots to see how flexible the squadron is and what would be expected of you.
You also could look at completing EWS or Command and Staff via a seminar as an option to earn points and assist with promotion. Speaking of promotion, you can easily get promoted out of the IRR, so be sure to keep an eye on the boards and throw in a package when you are in zone.
A few weeks of Majors pay every year is a pretty darn good part time job and break from work if you find the right gig, plus if you feel the need to serve during the next dust up overseas its much easier to find an opportunity if you stay active in the reserve community.
I hope this helps. PSN '03
