I see barely people using the anti tank mines, and in my experience I can see why. The Anti tank mines need a damage buff, as not even 3 of them is a guarantee kill on an APC or normal tank.
1 mine should bring them down to below half health.
2 mines should be a guarantee kill.
3 mines should overkill on a person you hate.
As well as changing the design of them to be wider and lay flatter to the ground to be harder to spot.
