So does IRR count as currently serving?

I resemble this remark. I served from 1970 - 1993 After first discharge I waited to for 2 years to go into National Guard on a try one. I waited 2 1/2 years to go to regular enlistment into National Guard and then moved onto Reserves, then USAF, then Reserves and 2 Mobilizations from 90 - 93. So essentially I should have 22+ years. However I did not qualify for retirement. The quick answer is that I only had 17.5 years toward Retirement and the 4.5 years in IRR status was not counted for retirement. Perhaps I should have requested a short tour each year on IRR status and I would be retired today.

For those of you who take a step back in the IRR for any reason, note that for every 3 hours of correspondence courses taken, it is 1 Retirement Point. I think the max is around 75 points from Correspondence Courses and that creates a Good Year toward Retirement. I wish I knew that then.
