"We’ve experienced several problems and delays with MAVNI’s preventing them from shipping to Basic Training. Now, due to another unfortunate turn of events all MAVNI FS, both Regular Army and Army Reserve will not be allowed to depart for training.

An additional level of background investigations is currently under development. Once created and implemented all MAVNI FS will have to be cleared under the new protocol, in addition to the NIAC and SSBI being favorably closed.

The Recruiting Operations Center has started renegotiating contracts for all current FS. RA FS are being moved into MOS 09U with a ship date of FY18. AR are being moved into the same MOS and unit with an FY 18 ship date.
(FY18 = 1 October 2017 through 30 September 201

Contact your recruiter, for an updated copy of your reservation. The FS website WILL NOT have the correct information."
