I also have a set of those on my painting queue. Khaki w/ drab pants is a really good look for them too, really compliments the red skin and gives them a proper military look. Makes em look like alien soldiers, not just alien invaders. I'm going for a similar scheme for my Haqqislam once I get around to them, though my morats will be standard black w/ red accents. Green skin for my Morats, I want some Space Orcs!
The game is quite fun, if complicated (in a good way). LOTS of special rules to get your head around. Finally got a friend into it with the new 2 player starter and playing those missions is a nice way to learn the rules. The Infinity message board has a thread about using Morats in the starter missions, replacing one side or the other with Morat equivelants. If anybody in your group picked up Icestorm and will let you borrow the missions/terrain then it's a great way to get playing, and you gotta love any company so confident in the quality of their minis and their printed books that they give you the full digital rulebook for free!
