Stalker was kind of a non-entity in the cartoon, but he was a major player in the comic book. In fact, for the first couple of years, he was one of the guys you'd most likely see in charge of a mission.
So, years later, when I got into Dungeons & Dragons and saw a character class also called "Ranger", I knew what that meant: they were a whole class of bad-asses. I'm not saying that Stalker is the reason why Ranger is my preferred D&D class, but I'm also not *not* saying it.
For Stalker, I used the EM4 Miniatures 0433 Trooper. MAR. Beret and I think it worked fine. Sure, my camo color is off a little bit, but what are you going to do?
