I just called ABC-C and they said that if your a Military Reserve Technician (dual Status MRT) and was hired after Feb 10,1996 the only way you can early retire is being 50 years of age and working as dual status technician for 20 years ( no military buyback counts towards 20 years) that means butt in seat working or any age and 25 years as a dual status technician ( no military buyback counts towards 25 years), this being a special provision for just Military Reserve Technician, Discontinued Service (DSR) does not apply to Military Reserve Technicians. DSR applies to those that are not in a dual status role or those who have to have military membership in their positions. So if you do not qualify to hold your military due to a medical condition, and do not qualify for a early retirement under the Title 5 U.S.C. 8414(c)(1)or(2) Early Retirement, then you would file for a disability retirement and even then if you don't qualify for that through OPM and get a denied response then you would file under the special disability provision for Military Reserve technicians called Public Law 97-253 and then your pretty much confirmed that you will receive your disability.
