i mean they will probably do that as well, but we are a way off from completely replacing humans for things like hostage rescue, seizing infrastructure without damaging it, acting in poor visibility, operating in theaters with contested electronic warfare capabilities, and other ambiguous, complicated, or politically sensitive tasks. especially ground drones don't perform well in poor visibility and unpredictable terrain. to make a drone cheap they use cameras instead of LIDAR, so its harder to program software to interpret the visual data. with LIDAR it would have distance data as well and could compensate for things like dust and weather and lighting at least. but then the drones would be too expensive to use in many scenarios. and remote operated drones can be hacked or at least jammed and cut off from commands, resorting to preset behaviors and retreat routes, more and more militaries and groups will have more and more EW capability as the tech is cheaper to produce.
