Body type 4 is just the body, not the face, and it's the "chubby" body type which is kind of hard to see in either of these pictures. I should take caps of the two from the character creation screen for comparison. It is sadly nowhere near as chubby as male body type 4 which is actually fat. But it's my favorite body type. (My trooper is body type 2 though.)

And nameplates are important ok. (It's especially hilarious in this instance though; you're right.)
