Sensor Arrays are yet another poorly documented feature of MAG. My understanding is that they can only be used by PLs for sensor sweeps of only a small part of the map - please correct me if I'm wrong.
If this is the case, they are about as important for the attacker to take down as motor pools - read: not very important. Actually the main benefit in this case would be to create a distraction when a lone commando takes it down and ties enemy resources in fixing it.
Any other Sensor Array tactics or other notes about them?
