502(f) for a period of 180 consecutive days or greater in order to provide full-time support to National Guard and Reserve organizations for the purpose of leading, organizing, administering, recruiting, instructing, or training the Reserve Components according to Subsection 101(d)(6).
But whereas Army and Air Force Reserve Component personnel can enter the AGR program at any point in their careers, entry into the sea service programs is typically limited to E-5 and below for enlisted personnel, W-2 for warrant officers, and O-3 or O-4, the latter with less than three years' time in grade (TIG) as an O-4, for commissioned officers.
[4] Approximately 95% of Navy TAR, Marine Corps AR and Coast Guard RPA officers and enlisted personnel enter these programs directly from the Active Component.
Senior officers in the TAR, AR and RPA programs are also subject to continuation boards at the O-5 and O-6 level and may be subject to an earlier mandated retirement date than their Regular Navy, Regular Marine Corps or Regular Coast Guard counterparts of the same pay grade in the Active Component or their "traditional" Navy Selected Reserve (SELRES), Selected Marine Corps Reserve (SMCR) or Coast Guard Selected Reserve (SELRES) counterparts in the Reserve Component, including the latter when recalled back to active duty.
Since September 11, 2001, substantial numbers of "traditional" part-time Reserve officers of the Navy, Marine Corps and Coast Guard above the rank of O-3 and senior enlisted at E-6 and above have been recalled to active duty for successive back-to-back or near back-to-back active duty periods under mobilization, special work or operational support orders, filling shortfalls for two, three, four, or more years for which no qualified Active Component or TAR officer or senior enlisted is available.
