Navy Reserve Full Time Support (FTS) verses Active Duty

FTS - Full Time Support (formerly TAR = Training and Administration of the Reserve).

Here is a post I did on that once: Full-Time Support –These are designated Reservists who perform full-time Active Duty service that relates to the training and administration of the Navy Reserve program. They may be assigned to shore activities and commands or operational units. They typically are not reassigned to different locations as often as those on regular Active Duty. And they receive the same pay, allowances and benefits as Active Duty members.

Here is link to the about.com page about that and the ratings that are FTS:

Also, this is from Wikipedia:
FTS, previously known as TAR (Training and Administration of the Reserve) serve in uniform all year round and provide administrative support to SELRES and operational support for the Navy. They are full-time career active duty personnel, but reside in the Reserve Component (RC), and perform a role similar to Active Guard and Reserve (AGR), Air Reserve Technician (ART) and Army Reserve Technician in the AirForce Reserve Command, the Air National Guard, the U.S. Army Reserve and the Army National Guard. Here is a link to the Official Navy Reserve site on the different kinds of reservists (SELRES, IRR and FTS. Also Retired Reserves):
