Sorry for the delay. I had to pull the reference. You can see the reference here
This is the DoD instruction that applies
Here is the pertinent language
(5) Active Duty Protection. In accordance with section 12686 of Reference (b), RC members ordered to active duty who, on the date they would otherwise be released from active duty, are within 2 years of becoming eligible for retired pay or retainer pay under a purely military retirement system other than retired pay for non-regular service under chapter 1223 of Reference (b):
(a) Shall not be involuntarily released from active duty before they become eligible for that pay.
(b) Shall be absorbed in Service-authorized active end strengths, unless the release is approved by the Secretary of the Military Department concerned.
(c) May be required, at the discretion of the Secretary concerned, to sign a waiver of the protection afforded by section 12686(a) of Reference (b) as a condition for issuance of active duty orders that are of 180 days duration or less.
The key is the term "active duty"
If you look at the glossary (it has definitions) you see that active duty is defined as
active duty. Full-time duty in the active military service of the United States. For Reserve members, it includes all periods of service pursuant to sections 688; 12301 (a), (b), and (d); 12302; and 12304 of Reference (b).
Reference (b) is Title 10
SO you need title 10 orders to qualify for sanctuary.
You can not claim it while on title 32 orders
Please let me know if you have more questions. I am happy to help if I can. Otherwise, please rate the answer so I may get credit for my work.
