During my 28 years of service most EngO's were only 'meeting engineers' who if handed a screwdriver would probably hold the wrong end. They would spend more time in an office staring at a computer screen (or in a meeting) than on the hangar floor, and were only sought if a red or green needed signing. Chiefs generally ran the enginering effort with the Warrant Officers' eye on them......and Flight Sergeants organised the guard duties. I often wondered what EngO's did pre computers.......attend metings and when in the office stare into space!
