Dang, son.
My only surprise/regret is that more people didn't do Goblins (or even Gnomes); the Little People are prime candidates for this whole "Squad" concept that you have aced.
As a Goblin fan & a Squad fan, I'm in love. As a word-lover, "Boom Squad" has me quite pleased (even though you didn't capitalize on it with
any explodey-goodness!? Even a Death-Explode would've been neat. :<...). The duo are not detailed enough to be separate units (well, at least not Heroes), but together they are just right. (I particularly love the gun-guy; he has a whole tech-backpack with a robo-armature ending in... A targeting-reticule monocle. Lol).
In terms of animations, it was quite resourceful of you to simply combine the Footman & the Rifleman; works really well (even for those who want this model to attack ground w/ sword & air w/ gun, all it takes is a little custom OE trickery & you're set). You even included a Portrait model (where's its a shame the gun-guy doesn't talk, but then again maybe he's the strong, silent type (or more likely, you just ran out of time

)).
It's a shame the new Hive/model viewer doesn't let us look at textures; I'd be interested to know where you found some of yours (especially that TC bomb?? How is
that in-game?)
Good luck in the Contest!
