>>>In a society with a strong concept of honor, both men would use similar weapons. If one was lacking such a weapon, the other would provide it before the fight started. That's what 2 Samurai would do. And why? Mutual respect, that's why<<<

I think that's where most movies get it wrong. I think that type of "honor" has been pretty rare through history. Every storied battle I can think of pitted a stronger foe against a weaker one. But in a lot of cases it was better weapons and "sneaky tactics" that won out. I'll bet the French say that Henry V "cheated at Agincourt.

Doc Holiday was not only faster than most. But he had the best guns available at the time and he cared for them like children. Should he have limited himself to using only the weapons he was faced with?

In WWI the brits beat the Germans by inventing the tank.

In WWII the Germans gained the advantage by building better weapons and having better soldiers. The allies countered with superior weapons and better and better pilots and other specialized soldiers.
