Final answer:
UAS such as the MQ-9 Reaper and MQ-1 Predator can be equipped with GBU and Hellfire missiles, which are military drones used for surveillance and targeted strikes.
Step-by-step explanation:
The question relates to the Unmanned Aerial Systems (UAS) that can be equipped with precision-guided munitions such as the GBU (Guided Bomb Unit) and Hellfire missiles. These are typically military drones used in various operations for surveillance and targeted strikes. The most common UAS capable of being equipped with these weapons are the MQ-9 Reaper and the MQ-1 Predator. Both of these drones have been extensively used in military operations for precision strikes against specific targets. The MQ-9 Reaper, for instance, is designed for long-endurance, high-altitude surveillance and can carry a payload including GBU series bombs and Hellfire missiles. The MQ-1 Predator, although now being phased out, was similarly capable of carrying these munitions. It's significant to note that the use of such UAS and munitions is subject to international laws and regulations concerning armed conflict.
