1. A laser-based visual disruption countermeasure network including a first helicopter and a second helicopter, comprising:

  • a hostile fire indicator subsystem on-board the first helicopter to identify locations of stationary or moving ground-based threats to a second helicopter and to generate respective ground-projection zones around the identified locations indicative of possible error in the identified locations,each of the zones around the identified threat locations being in the form of an ellipse,said hostile fire indicator subsystem on-board the first helicopter being configured and operative to send data representative of the generated ground-projection zones to the second helicopter in a same general area as the first helicopter; and

    a first eye-safe laser-based visual disruption subsystem on-board the second helicopter to generate and output a plurality of laser beams with intensities sufficient to interfere with and temporarily impair a human optical system,each laser beam being output so as to follow a rectangular scan pattern completely enveloping a corresponding ellipse defining the zone indicating possible error in a corresponding identified threat location, irrespective of current position of the second helicopter,said first eye-safe laser-based visual disruption subsystem being operative to maintain at the same time two or more of the rectangular scan patterns,wherein the network is configured and operative to determine whether a first rectangular scan pattern and a second rectangular scan pattern maintained at the same time overlap, each of the first and second rectangular scan patterns being output by a respective one of the laser beams, andwherein said first and second rectangular scan patterns are each modified by increasing applied laser beam energy of the respective one of the laser beams from a first intensity to a intensity only for any overlapping portion of the first and second rectangular scan patterns.
