A leader is always in the position of making the tough calls and hard decisions. Duke, as the head of the G.I. Joe team, understands the burden of leadership all too well. When it's the duty of the team to respond to a threat against the world, Duke must be the one to make sure that the priorities are clear: the mission comes first and everything else comes a distant second. He demands a lot from his team, but doesn't ask anything of them that he isn't willing to give himself. His hard-won experience and unflinching determination have earned him the respect and loyalty of his team.
This character doesn't have much of an established backstory. Unless contradicted by a canon source, you can assume their history mostly mirrors Duke (RAH)'s.
