I think we can lump these sorts of concepts together as "cyberpunk" military figures - more or less modern military uniforms, with futuristic assault rifles from "20 minutes into the future", for figures that would work for the likes of "Aliens" and "Starship Troopers". It would also fit an idea I've been bouncing around in the "Cold Warrior" discussion for a sort of "G.I. Joe vs. COBRA" conflict, and no doubt a lot of similar near-future military sci-fi concepts (I seem to remember similar styles of troops appearing in more overtly dystopian "cyberpunk" style movies too, like "Escape from New York" and the like: they'd make great villains for a dystopian rebel uprising type of scenario!)
And for the purpose of this sort of cyberpunk platoon, some kit-bashing between the Cannon Fodder and some historical "modern" figure bodies - anywhere from Vietnam era to modern era, or alternatively maybe even WWII or even WWI US figures - would get you in that ballpark.
Really, I think the "Cannon Fodder" kits would mostly work as-is - the only major thing missing from the "Cannon Fodder" being, perhaps, the futuristic combat armor of the sort you might find on some historical modern US or other military figures; the helmets (and caps), and the futuristic rifles, pretty much fit the bill perfectly, and the torsos at least would fit for vehicle crew and the like, at least. And the benefit of the Cannon Fodder is the upcoming complementary set of women troops, which seem to fit the template as well.
So, I'd say go for the "Cannon Fodder" - and the "Death Fields Accessory Sprue #1" (which has some carbines(?) in a very similar style to the Cannon Fodder's rifles, for some variety) and perhaps some othe Death Fields kits, like the "Grognard Command and Heavy Weapons" kit, Raumjager kit, and/or upcoming "Space Brits" set (which between them have some great heavy weapons) - for a starting place.
But, some US/NATO and Soviet/Russian solders from the Cold War era to present would really hit the target perfectly, I think, if kitbashed with the Canon Fodder into cyberpunk style "Colonial Marines", and Cold War and modernfigures would be a welcome addition to WA's catalogue!
