Vehicules receiving a grenade in the open hatch from a quad copter is so depressing. The small payload become insanely effective. Fancy 360 degree camera system on vehicule are fragile, subject to mud and shrapnels but stop ammunitions falling on your lap. With the profusion of UAV, climatisation and 360 view could become a necessary addon. Some sort of mini c-ram in small caliber with optical/infrared-guidance against the background, could be interesting against these and atgm.Quadcopter dropping a grenade on an open hatch of an M113. Seen a number of videos by the DPR and LPR doing this, and on trenches. Particularly favored by the Somali and Sparta Battalions. At times it's not a grenade but a mortar shell.
