What is the name of the form when you are released from the Ready Reserve?

Everyone gets a DD214 for a period of ACTIVE duty. National Guard has the NGB-22 to show a completion of service. From what I've found, there is no form for USAR unless you served a period of active duty.

Here's another thread that pertains to the same question.

Individual Ready Reserve aka IRR is an official status for Soldiers who've completed a tour of duty less than the current full commitment of military service. A service contract would read X years active and Y years ready reserve duty where you are subject to recall for national emergencies. Generally the DD214 would show your current service commitment completion and the DD 214 can be used to calculate remaining time of service. If you completed the full term active duty time with no Reserve Time remaining it should show as much on the 214. Otherwise the current documentation needed for Federal Reserve is either a copy of orders showing enlistment into the IRR after completion of a full service contract to show Non Drilling Reserve Status, or your DD 214. Its almost 30 years that what was know as hip pocket orders have been done away with. As for Reservists reaching their termination date. You need to check with your unit's S1 personnel section, to see if they still provide the release from service letter after you've completed your obligation. And yes, there used to be an officially published letter mailed to the soldier after the end of the obligation date to show no further service commitment, but I do not know if that is still done by HRC.

I have that one, it purely states initial active duty for training. However from what I gather most Reservists do not receive such form upon their release from the “Ready Reserve”
