Soldiers are authorized to mix and match T-shirts, belts, and boots with either the Operation Enduring Freedom Camouflage Pattern or the Operational Camouflage Pattern during the transition period – expected to run through Oct. 1, 2019. To further ease the change, Soldiers, who already have Flame Resistant ACUs in the Operational Enduring Freedom Camouflage Pattern, will be authorized to wear them during the transition.
the Army officially announced that OCP uniforms would be available in US Army clothing sale stores 1 July, 2015. They also released these slides which detail how the uniforms are to be worn. The information is in line with the draft ALARACT we recently spoke about except they’ve relented on headgear for the OCP variants which can now be worn with the MultiCam or Scorpion versions. You really need to go back and read the draft ALARACT story if you want to get in the weeds on this.
