My target audience for this post is those that crossed the rainbow bridge into reserve retirement.
The info above is pretty good. Only things to add are to check on the Reserve Component Survivor Benefit Program and make sure you have the proper election; also might want to write down and login once a month to your dfas / mypay account so it stays active until you retire. You may want to order your service records and medical records. Finally, you may want to call PERS-912 and have them send you a copy of your point capture total as a backup. Congratulations!
BTW: pension is Point Total / 360 x 0.025 x Base pay (high 3)
Base pay is determined by your point total. Even though you have your 20 good years, if you have 5400 points your base pay year would be year 15 (5400 / 360 = 15)
