When you play Command and Conquer or Starcraft, you're supposedly some anonymous commander at a console who can see everything and command everyone via some combination of technology and/or space magic. When you play Warcraft, maybe you're looking into a magic mirror. When you play Company of Heroes, uh, you're... uh... a plane is flying above and radioing battlefield recon back to HQ, and some lovely women in neat khaki caps slide pieces around on a map?...
As far as user interface framing goes, there's very little metaphor outside of fantasy magic and holographic virtual magic. Of course, none of these are "problems" in these games, because everyone knows it's a trick -- that is, we all know it's just some stupid bullshit that doesn't matter, and that's okay. ("Tetris doesn't need a plot!!!")
But the only way to coherently read this kind of fiction is to disembody it, to assume you're more like some abstract "force" -- maybe you're the collective human will to survive or collective unconscious manifestation of nationalism, some system of belief guiding all these people and resources toward some grand purpose that few of them can imagine. (Frozen Synapse imagines that you are literally "Tactics," the player character is the squad's abstract ability to think, perceive, and act.)
