On the other side of the coin, you have to have that arrogance and mentality to be a leader and a fighter in the first place, so unfortunately it is hard to have one without the other.
That is an oft quoted statement, but I'm not so sure I agree. Take the case of two commanding officers of 617 Squadron , Guy Gibson and Leonard Cheshire. Both were effective leaders and courageus pilots , but whereas Gibson was by all accounts an arrogant sod, particularly in his dealings with other ranks, Cheshire was renowned as being popular among all ranks,and was a sensitive and thoughtful man, as witness his post war work with the disabled which led to the setting up the Cheshire Homes. Definitely the exception that proved the rule.
