I am not sure how current your knowledge is. We already have antiair systems that wouldn’t give your loadmaster any chance to recognize the threat much less react to it. Chaff and flares only work on slower shoulder-fired heat-seeking missiles. There are also target recognition technologies that will differentiate between different types of hostile people and friendlies/noncombatants. It’s not 100% yet, hence the wait. Robots will eventually take up all combat roles - possibly within our lifetimes. Drones are only the first rung in the ladder.
I know a lot more than I can post here. Lets leave it at that.
