Future warfare is mostly unmanned. Usage of robots and drones for security purposes at the borders is now a reality. In the western world, US launched drone attacks in the recent past and majority of them were successful. China too invested and researched on usage of drones in the military.
After Pakistan shifted sides from USA to China for war equipment, the country bought the drone technology from China. Recently, drone related surveillance on Indian territory at the Indo-Pak border is observed by the Indian Army. China is aiming to supply four high end attack drones to Pakistan. To counter attack this sort of a threat, Indian Government is planning to buy the most advanced war drones from USA.
Predator-B drones which are being supplied by USA may now appear in India soon. DRDO too is working on Indian made drones but to counter attack the immediate threat, Indian Government is planning to buy the drones from USA.
