Described embodiments include a real-time system, method, and apparatus. A system includes an incoming object sensor configured to be worn by a human and to acquire data indicative of a trajectory of an incoming projectile. The system includes a warning device configured to be worn by the human and to provide a notification to the human. The system includes a processing circuit configured to (i) receive the data indicative of a trajectory of the incoming projectile; (ii) predict a spatial relationship of the trajectory of the incoming projectile relative to the human; and (iii) initiate a notification by the warning device suggesting a movement by the human to evade the incoming projectile.
