Being a pyrotechnic device its use is limited by the flare burn time for catching the attention of a potential rescuer. They are more useful at sea or in open areas where they can be quickly and easily spotted.armoured soon said:these were from the Korean war as far as i know. my grandfather had them when he was on a ship.
