Hi there, Playgrounders!

I am trying to construct a character for a mercenary-themed campaign. I am hoping to be useful in a few aspects to the party, specifically as a mixed melee/ranged spearman who can deal decent damage while still being a functional scout for the party. I have a concept for a fighter/rogue/master thrower, but I was wondering:

Are there any better ways to fill a combat role like this? Specifically, with a better class? I'd like Hide/M.S., Tumble and UMD to be available options.

ToB may be allowed, most other books will be allowed, but I don't want to mess with psionics.

So, GitP, what can you do with a shortspear warrior? Javelins and darts also fit the theme.

Thanks for your time and help!
