Nothing says "badass elite operator" like Str 2 and Int 2, huh?

I'd worry a little less about trying to be
just good at combat, and look into making a character that can spot the bad guys coming, react in a reasonable way when he sees 'em, maintains a reasonable level of fitness, etc, etc. You're not going to always get to stomp around in your highly visible SWAT armor, after all, so don't let yourself fall into the one-trick-pony trap.
