I generally ignore the stat, because I haven't noticed any difference.
Is there a notable difference between like a big LMG with low maneuverability and a small SMG with high maneuverability? Like does it effect movement speed or something? --- Underwater Spartans: http://www.youtube.com/watch?v=Djp5dtz02eQ&feature=plcp
With the lag it really does NOT matter. It only means how fast your soldier will move. How fast he will run. I don't think it changes the cover pop out and shoot speed at all. Just the running and moving around aspects in the game.
So yes it affect movement and speed......aka maneuverability. --- NEW Video Game Remakes Uploaded http://www.youtube.com/user/sknocturnal
