3-5-7 or 3-6-10 and have the choice to customize so it brings some good aspect of Mw2.
3= UAV/Counter/Ammo Supply
5= Artillery strike/Motar Strike/Something like a Predator which is controllable
7=Helicopter/Tank 2 mins can be destroyed by 2 rockets or 1 c4 if they are shot at a critical point of the tank/Machine Gun pit its like the sentrey gun but u are the sentry gun
