If you're a prior service reservist and reenlist to AD, how much time to you lose, if you lose any?

I can actually speak from experience on this one. There are some things that get readjusted....like your BASD and the like. One thing that does not change is your years of service for pay. Time for retirement is affected but not time for pay.

SN Kevin Neff I believe the only consolidation in a Res-to-AD enlistment would be the retirement points you have already earned as a reservist. You would still be required to complete 20 years AD for pensioned retirement before age 60. Check with a Personnel Tech to be sure. As a reservist you can retire after 20 years of combined Res and AD duty (Ret-2 no pay status) with limited benefits, and you would have to wait until 60 to collect retirement pay (my situation).

It depends on what your time IS. If you have been mobilized and deployed the whole time it will all count as AD time. It's a case by case, record by record evaluation.

Kevin, it appears you have receive expert advice on your question. As stated by others your total years in the Reserve will count towards years of service for pay. However, you will have to serve 20 years active duty to qualify for retirement. If you deployed that time may count towards those 20 years. If you would revert back to reserve status your active duty time would count towards a 20 year reserve retirement. As CPO Carrillo advised, check with your personnel tech. Retirement options have changed and may continue to change and you need know and understand all of the facts.

As everyone else has stated, your years of service for pay does not change. Regarding retirement, reserve retirement and active duty retirement are essentially the exact same thing except reserve retirement you can not get until age 60 (or up to five years earlier based on years of active duty service). Active duty, you get 2.5% retirement for every year of service. Reserve retirement, you get one point for every drill or day of active duty, and you can accrue additional points by taking certain tests, volunteer pay, drilling for points (if allowed), etc. Your total number of points is then divided by 360 to get the equivalent of years of service, and the 2.5% multiplier is applied to that.

All of your reserve points will be counted in regards to your retirement pay relative to the formula I mentioned above. I believe a "good year" is at least 50 points; you get one point per drill, two drills per day, four points per "reserve weekend"; so 48 points a year from drills. 12 points are given for the 12 days of ADT required on an annual basis (travel day does not count), which bumps it up to 60. And 15 points are awarded on an annual basis at your anniversary time. Most people get 75 points a year, so you can roughly equate every year of reserve service as 0.5% retirement pay. If you're a career reservist with perfect years and having never been activated, you're basically entitled to 10% retirement pay. Years of active duty and being activated bumps that number up.

The new retirement system may change some of these things regarding the amount of money received, but otherwise, the standards remain largely the same in needing 20+ years of active duty service for an active duty retirement.
