When it comes to the newest gadget in the market there is no denial that drones, or unmanned aerial vehicles, top the list. They first attracted the attention of people at large when the US army used it for targeted operations to tackle terrorism. Drones proved very useful in searching terrorist camps and destroying them. The main advantage of using drones in the battlefield is that they do not carry a pilot. They are totally unmanned and thus there is no loss of life during the battle if the drone gets shot down by the enemy.However, it is not only the military that uses drones for their benefit nowadays. Even the common man is benefiting from the use of drones as they are being used in many other fields, such as housing, agriculture and photography.
