Description

  The present invention instantaneously irradiates an IFF (friend identification) laser beam to an ally classifier attached to a teammate when shooting a small firearm (handgun, rifle, machine gun, heavy machine gun) performed by a team member. The present invention relates to a laser ally identification system for discriminating allies.

  Conventionally, in the case of engaging with small arms, there is no technical means for identifying a friendly unit and an enemy unit, and the position of the own unit is generally confirmed by a wireless system. Unlike field battles, it is more difficult to determine the positions of allies when the placement of members changes with time, as in city battles, and it is extremely difficult to instantly identify teammates in engagement. Because of this, there was a risk of accidentally attacking allies.
