Smell something stinky? It's probably Private First Class Nicky Lee, aka "Tunnel Rat" -- an offbeat medic who grew up exploring Brooklyn's subway and sewer tunnels. He's still totally at home in dark, and gross places in general. Tunnel Rat knows more than anyone about dirt, worms, bugs, and whatever else is underground. He's got a major attitude, but he's also a funny guy. Seriously.
