Militaries employing Micro and Nano air vehicles to support Soldiers in tactical operations on battlefield

Large UAVs, such as  Global Hawk,  General Atomics MQ-9 Reaper, and predecessor MQ-1 Predator have already become indispensable to modern militaries in providing intelligence, near-real-time reconnaissance and surveillance to commanders, and offering warfighters greater battlespace awareness. They have proven effective in electronic combat support, battle damage assessment, and even in national security operations like border surveillance, low-intensity conflict, and guerilla / terrorist warfare.
