Adding to the fire....during Vietnam...a flying intensive exercise in futility....the US Army had the exact same attitude about secondary duties for Warrant Officers even. Never mind you were the Unit Standardization Instructor Pilot, flying training sorties in addition to a full slot on the the ops board....one had to have a secondary duty....to the extent extra duties were invented in order to provide you that opportunity to excel.
Don't get me started on other aspects of the brain dead being in charge....like "Zero Defects".....or "Scripted Exercises"....or does the RAF and British Army still embrace those concepts too?
At least the US Army finally went to free flow training....where events are played out as they happen....and one side loses....and it can be either side....and not done by script.
