What device provides live real-time video from aircraft directly to supported units?

The Remotely Operated Video Enhanced Receiver (ROVER) is specifically designed to receive live real-time video feeds from aircraft. This capability allows supported units on the ground to access vital aerial surveillance and reconnaissance information as it happens, enhancing situational awareness and decision-making. ROVER integrates with various aircraft and can display video from sources like drones or manned reconnaissance aircraft, which is crucial for time-sensitive operations in the field.

While the Advanced Targeting Pod and the Battlefield Airborne Communications Node serve important roles in providing targeting information and communication, respectively, they do not focus exclusively on delivering live video feeds in real time to ground units. The Ground Control Station is primarily used to control unmanned aircraft systems rather than to provide direct real-time video feeds to users. Therefore, ROVER stands out as the correct answer due to its dedicated function of streaming live video directly from aircraft to support units in operational scenarios.
