I think that there's a difference between bullying and aggression. I can think of many mild-mannered, wouldn't-hurt-a-fly colleagues who, when they stepped onto a rugby pitch were transformed. Unless you're a front line fighter pilot you're supporting someone else's fight. In my experience (support helicopters) the difficult thing about military aviation in a combat role is overcoming your fear and having the courage and discipline to carry out your job. My students showed their mettle time and again in combat, all I could do as their instructor was to equip them as best as I could for their frontline role. It often took patience and occasionally a little ingenuity to get my point across but a I never once even raised my voice or lost my temper; it would not have achieved anything. The guys and girls were invariably trying their best and I was simply there to help them. I cajoled, encouraged and chided until they achieved the required standard. On the the very odd occasion when they failed to meet the standard and were withdrawn from training, I was as gutted as they were. Of all the aviation disciplines I can honestly say that instructing was the one that gave me the most satisfaction.
