ISIS whenever they launched attacks in Syria or Iraq against some army base or prison structure they filmed it with drones and put it on youtube. Their strategy was multiple suicide trucks or cars filled with explosives (some were decoy vehicles) that had to survive the speeding attack to the walls to blow themselves up for a breach where the foot soldiers could come in and raid, so these were mad max looking vehicles covered in makeshift armor, coming in from all directions hoping to exploit a blind spot in the structure's defenses. So in other words having no blind spots seems like the best defense against that kind of enemy or one that tries and lobs mortars at you while you have clear sight of them doing so.
