In a ground war, what much more tactically advanced technology does the US have that is such a game changer, it will guarantee us victory? Do our tanks, which I hear we are getting rid of, have covenant cloaking devices? Do our helicopters?
As for "cyber hacking", yeh sure we can hack each others emails during peacetime, when the only topics the top brass are discussing is what they are doing this weekend, or which drill and who will be running them today, (while practicing secrecy for the sake of it) but I imagine during wartime, the lines of communication will be more secure and not via the world wide web.
