A network for indicating and communicating detection of hostile fire, and systems, methods, and computer program products thereof. Hostile fire is optically detected and identified at a first vehicle and such identification is transmitted from the first vehicle to one or more other vehicles in the network. Data regarding hostile fire directed at the first vehicle can be stored at one or more of the other vehicles and even retransmitted to other vehicles or base stations.
