The U.S.army recently awarded a contract for micro-unmanned aerial vehicles (uavs) to enhance the infantry's small-scale combat capabilities as part of a pilot program to validate future infantry-based information operations.The total amount of the contract is not bad,reaching 269 million yuan.But the unit price,a tiny helicopter not much bigger than a finger,was quoted at 270,000 yuan.And a complete set of black bumblebee uav system,including two drones,remote display terminal,charging seat,the price is more reached 1.325 million.

  Because of its small size,the drone is low in noise and difficult to detect.But again,with a very limited battery capacity,it can support up to 25 minutes of flight.Its main function is to send back real-time video, as well as static photos;The longest transmission distance is claimed to be 2 kilometers.But even considering the small size of the uav,it must be very difficult and costly to detect and transmit the video data at 2km with encryption.However,the price is really very expensive.

  In recent years,the popularity of small and micro uavs has had a subversive impact on the tactical system of infantry combat.The idea that such low-level,small-scale infantry groups could be supported by air intelligence at any time,even though it had been envisioned in the U.S.military for many years,was not new.But true maturity, however,is relying on cheap civilian drones - especially the popularity of quadcopter aircraft,the formation of a spontaneous battlefield in various countries.

  The biggest problem that used to plague the decision-making of JOESCO is where the enemy is,where they are going, and where their observation and firepower are weak.The side with drones is playing tactical games from god's perspective.It would be difficult to shoot down these small aircraft with a firearm,and even if they were shot down,they would be able to quickly resupply drones because of their small size and low cost.
