While this is true on many maps a good tanker will using Thermal Vision, completely ruining the effect that a AT mine might have. Fort instance on SEINE where there is no threat of helocopter attack, they dont really need Smoke, so they can run Thermal and shoot up any AT mines before theyh come into play.
Javelin and laser still very effective. If there are no aircraft in the game i will have the javelin on and take them down very quickly. If they are a smoker then I will do it manually with the RPG. Mines are also very easy to hide within objects.
