Though I've never served in armed forces, nor participated in armed conflict, I think C&C does a pretty good approximation of being an (overwhelmed) officer in command of a small area conflict, where you do have to give exact orders to everyone for every little thing.
I think a huge improvement to RTS in general would be allowing multiple players to command the same army, so that each can be responsible for a small portion of all the different tasks you describe.
