Active Protection

Active Protection is a "hard-kill" countermeasure that neutralizes incoming anti-vehicle weaponry using infrared sensors and explosive interceptors developed by Israel Military Industries.

Battlefield 4
"When the system is activated it will sense incoming missile and rocket threats and detonate them before they reach the vehicle. The system will enter a cooldown state after a threat has been neutralized and no other threats have been detected for a short time."
