Technically, wearing PA makes you a tank.. unless your being shot in the head by a high caliber rifle, or being shot by a laser, plasma, or tri-beam rifle. But, there are exceptions. The user of the power armor's hands are unprotected, rubber gloves covering them, and the helmet can be destroyed rather easily using laser weaponry, and can also be destroyed by bullets if you somehow manage to hit it enough times, considering that your probably going to be getting shot at by the user if your attacking. By the way, keep in mind that the lensces of the helmet are bullet proof, true stuff, mang.
