Name: Stormtrooper, Imperial Gunner, Death Star Trooper, Rebel Soldier...
It's a long list, just look at the picture, and that is not all of them.
Rank: Various, even more than the names

    These are the guys that rarely get a name.  If they are one of the few lucky ones, their names are normally generic like Trooper-1 or Some Guy.  We can't let ourselves get attached to them because we know that they are most likely going to die shortly after we see them,  that's why we call them Cannon Fodder.
