i was wanting know if the marshal has any offensive boosting talents or if their knowledge based like investigation i was thinking of making a mashal/soldier sniper and use pistols i thought that would be cool any help would be great.

Yeah, they look pretty badass.

As the tree shows, most of his offensive ability is in the right-hand column: much like the movie version of a Wild West sherriff, he's primarily adept at sudden, short-range pistol gunfights.

Interestingly, he's not necessarily designed to be a quick-draw artist; Scoundrel gets Quick Strike, which gives him bonus damage when he shoots first, as well as Rapid Reaction, which helps with Initiative, but the Marshal doesn't. However, he does do extra damage at short range.

then i mite be a scoundrel marshal or fringer marshal

A Scoundrel/Marshal focused on the right-hand paths in each would be extremely skilled a sudden, short-ranged gunfights.

The reason he doesn't get a bonus to strike first, is that he's an officer of the law. He isn't supposed to start shooting until someone is shooting at him. He shoots second, but he hits harder.

Oh, I think the talents in the two trees suit the concepts very well: the Scoundrel strikes first in a short-range gunfight (for example, a card game gone wrong), and the Marshal is trained to drop suspects when things go badly.
