U.S. Air Force cheap. Airmen their pay to be cut?

"Military Pay Cut: Air Force Airmen’s Salary is Next"

"SOFREP has just reported about the pay cuts for Air Force recruiters that amounts to $900 in losses in their annual salary. We have also extensively covered the marketing problem in the military’s recruitment and the massive challenge of different US military branches failing to hit recruitment numbers for years since the Iraq war. Still, we have learned that military recruitment woes are not stopping there."

[....]

Here is a list [only partial.] of Air Force positions that would receive pay cuts starting Oct. 1:

" * Recruiters * Basic * Military * Training instructors * Human Intelligence debriefers * Combat Controllers * Pararescue operators" 

AIR FORCE PERSONNEL ACROSS THE BOARD PLEASE BE ASSURED THAT YOUR BASIC PAY FOR TIME AND GRADE NOT GOING TO BE CUT.

SDAP only for personnel with certain job skills beyond norm. 

Back in my day you had additional add-ons to your basic pay to include [but again not limited to] overseas pay, hardship tour pay, parachute pay, demolition pay, proficiency pay, etc.

PAY CUT nor ordinarily as we understand a PAY CUT!
