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 and O-4 with less than three years time in grade and below for commissioned officers. Approximately 95% of Navy FTS, Marine Corps AR and Coast Guard RPA officers and enlisted personnel enter these programs directly from the Active Component. Unlike the Army and Air Force AGR programs, the FTS, AR and RPA career tracks are considered permanent active duty career programs, with no opportunity for senior enlisted or senior officers to enter later in their careers from "traditional" part-time Reserve status at the E-7/E-8/E-9, O-5/O-6, or General Officer/Flag Officer levels. Senior officers in FTS, AR and RPA 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 Reserve/Selected Reserve counterparts in the Reserve Component, including the latter when recalled back to active duty. Since September 11, 2001, "traditional" Reserve officers of the Navy, Marine Corps and Coast Guard above the rank of O-4 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 FTS officer or senior enlisted is available, or individuals in the Reserve Component with specific talents and/or experience for whom the Active Component senior leadership (typically at the flag officer / general officer level) has made a "by name" request. However, career tenure (other than for Reserve retirement) and an active duty retirement, while occasionally achieved by these personnel, are not guaranteed. Navy Reserve Canvasser/Recruiters are also included in the AGR definition, but may be accessed at the E-7/8/9, W-2/3/4/5, O-4 with more than 3 years time in grade, and O-5 pay grades. Unlike FTS, Canvasser/Recruiter is not considered a career program, so career tenure protections and an active duty retirement are not guaranteed.
