Thanks for those pics hubbabubba and Ultravanillasmurf!
It would seem that the Raumjager may be significantly larger than the cannon fodder with the Stargrave falling in between.
Not sure about the Raumjager (I agree that it seems offputtingly large), but it does appear that the Stargrave Crew/Merc/Trooper parts would be compatible with the Cannon Fodder. I rather like the generic look of the Cannon Fodder, though unless I wanted a uniform crew I might just buy more Stargrave Crew sprues.
In a similar vein, I've got a sprue of Proxie troopers coming in that I plan to combine with leftover Stargrave arms and heads. Will post a pic when I do.
I haven't been paying much attention to wargames minis the past few years, but it seems like now we're in the midst of a golden era for affordable plastic figures. A few years ago -when Defiance imploded and Wargames Factory collapsed and their stuff went to Warlord where it tripled in price- I was pretty sure the days of $1-1.5 modern and sci-fi figs were over. I'm pleased to see that's very much not the case.
