Hi guys, I work with the Apache Helicopters and we use strobes for a number of uses such as identifying friend or foe, identifying Pick ups / drop of points and for search and rescue. A flashing light is easier to see from the air, through fog / low cloud, is omnidirectional (360 degrees viewable) rather than a torch which is limited to where you point it and greatly increases battery life, for instance if your on a mountain and have an accident you can turn your strobe on and even if you lose conciousness your little friend will still be shouting ' i am here' for rescue for days. I must add that when we use them tactically we cover the flash with a Infra Red cover which makes it invisable to the human eye but still visable to us with Passive Night vision goggles / monocule. Sneaky beakies can place them on their helmets before battle so they can still be seen by supporting troops /aircraft/ drones so we can offer fire support to our guys whilst distinguishing them from the enemy. Hope this helps!
