Should Cyber Warfare Have Its Own Branch?

Absolutely, yes. We need a new cabinet post in the Administration to govern IT in all aspects of the government including an Assistant Secretary for Cyber Warfare, one attack and another for defense. And we better do it soon.

Cyber can be a force multiplier without being its own domain/battlespace. Whether or not it needs its own command is an open question, particularly since cyber is poorly defined. But a whole branch? No. I don't think so.

No. Major Commands in each of the Services? Yes... eventually, when we mature. This may eventually lead to the decision to create a separate service, but I don't think we're quite there yet to even consider such a move.
