The Indian Air Force is now using new drones called Heron Mark 2 at a northern base. These drones, made in Israel, will help see if anyone tries to come into India from China or Pakistan. The drones can also attack if needed. They can watch both the China and Pakistan borders at the same time. The Air Force calls these drones the "Warden of the North." They can communicate using satellites, work in very cold weather, and can stay in the air for a long time. They can also see things even if they are very far away.
