Super snipers???

Guys consider that a sniper's "freedom of movement" when trying to escape detection and remain pointed on a target, can very well go unnoticed in 50m-hexes. Same with tanks or airplanes and invisible "evasion manoeuvers".
However, consider that even with a relatively high speed (generally 6) it will be hard for a human player to relocate a sniper team under fire (or nearly so) without losing either his positional advantage or the sniper or both.
