Also, it seems that several year groups are "safe" from the RIF based on the less than 1 year TIG or on a promotion list stipulations.
New Capts are out of luck since they have less than six years in, but '03 just finished pinning on O-4, '04 is on deck with the first line numbers starting in Jan (slowly), not to mention the guys pinning on/on the list for O-5 (99-2000 year groups?)
Edit: According to PSDM 13-130, it looks like the '03 year group is vulnerable to the RIF based on the less than one year TIG prior to 31 Jan 2015 stipulation.
