I’d also point out that you can adjust the “speed” of army movement — at least in TW: Warhammer — so that if they’re moving more quickly, like a forced march, they are less likely to spot hidden or sneaking armies. This does leave the mechanic depending on user choice of where to focus, not just ambient fog of war. It at least gives a similar state of mind as in SC where the player says to himself “do I go in with blinders on or do I proceed with more attention to surroundings” with real pros/cons for each.
