Even if it could, employing the mechanism of recoilless rifle would eliminate it.
Here's video. Nice to see because I wondering how much the recoil from a gun being fired would affect the UAV. It's look likes it hardly does. Now how would a .50 sniper rifle do?
Golden marketing opportunity to name these assault rifle flying drones as Murder Hornets. Imagine swarms of them coming at you.
During Desert Storm, an Apache attack helicopter crew made history by being the first and only aircraft to have taken infantry prisoner when a load of Iraqi troops flagged them down to surrender.
Would not surprise me if these drones, or something like them, also make history as the first drones to take human prisoners in future combat.
