You do bring a good point. Also, the Xenomorphs would probably instigate it, since the Martians would be unable to consume Xeno blood.

You do forget one weapon though: The teleportation ray. It was introduced in War of the Worlds 2, the Next Wave. Honestly though, it is likely only programmed to send targets to a Mothership. That said, after the first invasion, Martians switched to remotely controlled tripods, so it is unlikely that we will see any Xenomartians.

Unless we get more info that would give Martians a better chance, Xenos likely will win.
