One of the guys I'm managing has bad B.O. Basically, anyone who gets within 3-4 feet of him can smell him, and he STINKS. I've received numerous complaints about him from other coworkers. Is there anything I should/can do as his manager?

Simple; you're a manager, so manage. Take him aside, and tell him point blank. Tell him it's bad for morale, and reflects poorly on both of you. And this is key: assuming he is otherwise a valuable employee, preface your statement by making sure he knows that.
