US Military service: Army- Green Berets, Delta Force
Relationships: deceased wife, also has 7 other on-screen relationships
Is he in Andy Dalton's or Tom Brady's situation when it comes to supporting cast? Half-and-half, sometimes he has the help of CTU and the government but other times he is largely on his own and/or on the run

_____________________________________
Thinking things over a little more, the comparison among Bauer/Bourne/Bond isn't so straightforward. They each have an edge in their own way.
Bauer is the most patriotic and heroic, obviously. In terms of accomplishments, his resume dwarfs that of Bourne and Bond. He's also been through the most, in terms of acts he's had to commit and the demons he's had to live with after those actions.
Bourne would be the winner in a straight-up 3-way battle, whether martial arts or shooting or otherwise. Bourne and Bauer are about equal shots (and better than Bond), but Bourne is easily the martial arts winner. If Bauer were about 15 years younger, he might be equal to Bourne in that regard, but that's not the case.
Bond is the clear winner in terms of dressing well, being suave, drinking martinis, having the ladies, being gifted with all the support he wants at his disposal, etc. Some would view that as more favorable, while others would view that as detracting from him.
