Well, I had said that I was going to use the jumpy carbine spartans as Assault Squads, and I am!
The red guy is going to be the Squad Sergeant. I have just enough red Spartans to make most of the Sergeants be an appropriately armed red guy. I thought I had 10 total jumpers, but I was only able to find 9 of them when I went to take the picture, so hopefully the last dude will turn up, or else I will just use a five man team. Is there any point to taking extra bodies if you cannot combat squad them? I will admit to not having given it much thought. Time will tell.
