Having not been in the military, when I think of an illegal order, I am thinking of mowing down unarmed civilians or something like that. It will be interesting to see if the duly elected CIC could infact be found to have issued illegal orders because of his birth status.
I may be nit-picking here, but if the CIC is not eligible he cannot have been duly elected.
Obama did not order him to deploy, and all the wild claims that 'the buck stops with Obama' will not change that fact. The order to deploy came from somewhere in the administrative bureacracy of the Pentagon, far below the office of the President, and unless LCOL Lakin can prove that any of those people in his chain-of-command hold their rank illegally then he doesn't have a leg to stand on.
It's the "duly elected" part that is at issue.
