I would wager that 3% could be recouped by eliminating all the touchy-feely sensitivity training and GLBTQXYZ outreach and support programs.
Even if eliminating the “touchy-feely sensitivity training and GLBTQXYZ outreach and support programs” and the trannie coddling didn’t save a single dime, that alone would do wonders for military morale and capability. Getting the mission back to “breaking things and killing people” and sacking the feather merchants would restore our once-great military at zero cost.
