Joe Chapa in War on the Rocks:
Today, the U.S. Air Force “sunsets” the Predator, permanently retiring it from service. Though individual squadrons have been transitioning from the Predator to the Reaper for some time, that transition is now complete. This provides a good opportunity to look back at the Predator to learn what we can of its impact on contemporary war and on future combat.
Few weapons have changed warfare the way the Predator drone has.
