I was wondering, do they have to be humanoid? I've been thinking of making a robotic type of solider, but it was never explained if they have the technology for A.I or the use of them at all. Well, they probably have made them at some point with all the fancy gadgets and technology they have, but I was just wondering if I could do so and all of the special implications if an A.I can even join the military.

To be honest, that never even occurred to me. How advanced the AIs they'd have by then would be, hmm. I think an AI/Robot character would be fine, but it would be lacking in some fields that a normal living person would excel at, naturally (Pun intended), but could still prove invaluable to have. I think I'll allow it, so long as you give a reasonable history to it. Beyond that, keep in mind the limitations an AI would probably have and you should be fine.
