I think you could argue that the ground war (and ground attack) in AH isn't much like RL to begin with. Very limited vision, no spotters, no intel reports, no armored divisions advancing in mass, no maps showing enemy positions, no briefings, no tracks on the ground, no vehicles specific to one country, no support convoys to destroy and render tanks useless, no ammo and fuel depots, no bridges, no roads, no nothing. All we have is that icon when we get within 2 miles. I don't see a point in giving the GVers an advantage here, but that's just my opinion.
