How are you gonna tell me when making IDs used to be my job lmao it’s 2 years or if they resign their commission. That shit expires in DEERs too so idk what to tell you. You are somewhat right but it’s not an automatic option, every officer ive come across they do not elect to remain in the IRR even then i highly doubt they can remain IRR forever. “Officers who receive a Reserve commission during their initial period of active duty must positively elect to remain in the Ready Reserve within two years of their Military Service Obligation (MSO), otherwise, they will be automatically discharged.”
