Those “equipment related reasons” are nothing that AAG couldn’t choose to change. IDK for sure, but I doubt that every RAH plane flown for AAG has the overwater equipment. Envoy could change opspec and carry the equipment on just enough aircraft to cover the flying. Does it make logistics slightly more difficult, sure, but it can be done. Envoy had a choice of Canada or Caribbean. They chose the Great White North. They didn’t want the weight penalty for the overwater equipment. But again, I don’t think they would have to equip the whole fleet. But either way, it’s a strategic choice.
