Unmanned aerial vehicle technology is advancing rapidly, and drones are getting smaller by the day. Militaries are now employing Micro, Mini & Nano UAVs into their operations. They provide situational awareness to a small group of soldiers by flying several stories above them for 10-20 minutes at a time before placed back into a pocket to recharge. These will be used to carry out tasks in urban environments, such as deliveries, surveillance, and search and rescue. Small drones are considered better because they are more agile, are harder to detect, and are easier for pilots to control.
In August 2019, US Army troops in Afghanistan deployed a new reconnaissance tool: palm-size drones that weigh just over an ounce. The Black Hornet remote-control micro-copters stream hi-def video and photos, and their diminutive dimensions—and ability to fly without a GPS signal—make them especially adept at ducking into buildings, bunkers, and caves. Black Hornet PRS transmit live video and HD still images, providing soldiers with real time battleground situational awareness. This helps personnel take informed decisions and increase the efficiency of the mission. Till date, the company has delivered more than 12,000 Black Hornet nano-UAVs to defence and security forces across the globe.
