I'm most proficient at the G36 assault rifle and the MG3 machine gun. The army does that to you. I've spent more time with those weapons than any others. If I get to keep my glasses on, I'm a pretty damn good shot, too. Being an engineer, I can also make things go boom really well, if given the chance.
Besides that, I have full proficiency in the AK series, the M16 and the M5. I'm far more able with assault rifles than sub-machine guns, though. [small]That's why I should not be the one clearing out buildings.[/small]
In addition to all that, I'm extremely well-versed in the H&K USP, the pistol I used back in military courses and the one I currently own as my home defense weapon of choice.
I also own a lovely bolt-action Mauser M98 Magnum. Only to be used for hunting and firearm practice, of course.
As for hand-to-hand combat, I am decent at bayonets and my infantry officer's parade sword. My fists are far more deadly than either of those, though. Years of self-destructive tendencies can do that to you.
Good God, I really know too much about those things.
