i've mastered the tank mine so here's how you do it.
1) if you have the explosive perk use it, it gives you 6 mines instead of 3.
2) have a support guy give you more ammo and you can have unlimited mines pretty much. As long as you fill from a crate you can keep getting your mines back and can create a deadly mine field.
3) Placement is key. Stagger your mines and space them out so that the vehicle will hit a series of mines. Best way i can describe my setup is picture a checker board. Now picture just the black squares on the board. Set your mines up like that.
#2 is probably the main key here though. My friend plays support and between me and him we can pretty much keep the other teams ground vehicles from ever becoming a threat
