I remember one particular night a young luitenant who should have lived had bled out while our bird waited for ~30 min on the ground in Bagram for an Apache to return from another mission. The Apache of course then had to refuel. This, before it made the 40 minute flight to the secure LZ to pick this soldier up.
Of course neither this nor the case you spoke of was the crews' choice. They're borderline crazy on the things they'll attempt to help the kid with the rifle on the ground and those stories are countless. But as it goes, "rules are rules." This is the last place needing even an inch of red tape.
