Any of you guys have ideas for skills a marksman might have? I'm turning up a blank after 'Shooting a gun' and 'Parkour/free running'.

Well, a marksman or sharpshooter is someone skilled at precision shooting using projectile weapons, typically a rifle, to shoot at long range targets. In the military for example, marksmen are part of a fireteam or squad, where they take accurate long-range shots at valuable targets(usually non human, unlike snipers), thus extending the reach of the fireteam. The main difference between marksmen and snipers, because some people have the tendency to confuse them and think they are the same thing, is that marksmen are considered an organic part of a fireteam of soldiers, while snipers tend to work alone or with an observer, or sometimes even with other snipers.

Now with that being said...regarding your character, I don't know what character you want to make. If he's an ex-military you can just add military training as one of his skills because that pretty much covers everything regarding combat, weapons knowledge and usage, hand-to-hand combat, close-quarters combat, tactics, strategy, physical training, and so on. As for the other two skill options you can add whatever you want, it dosen't have to be something regarding combat, because you already have military training which makes you a dangerous person right from the start. 

On the other hand, if your character was not in the military you can just add weapons knowledge, marksmanship, and for the 3rd, your choice, it dosen't have to be something regarding combat, but you'll have to motvate in the bio how you got those first 2 skills without having military training. 

I hope what I wrote was helpful! :)
