Cyber Space is still space, no? That was my thought. When President Trump said Space Force, that was where my mind went. A military branch whose primary mission was cyber security, could include space above earth like NASA with weapons too. Think of how the tactics of war are changing. It's no longer primarily guns, bombs and tanks. Imagine how much more damage you could do to your enemy by taking control of their weapons systems, utilities, etc? You could render your enemy helpless without firing a shot.
