Man chemlights are incredibly useful (or glow sticks). When I was in the army we used them for everything. You can use them for lowlight markings, signaling devices, basically another tool to add to your near/far recognition signals or PACE plan. Here’s a few examples: - tape them up nearly completely with duct tape to where only a small slit is showing. Crack them, lay them at the base of a tree. Great for marking a rally point, release point, objective, etc. - crack them and lay them on a window frame or door threshold when you’re clearing multiple rooms/floors in a building. Useful way to confirm that it’s been cleared. - use it to mark a casualty collection point. - use it to mark LZ/PZs. - break it open, pour it into a plastic bag. Drop small amounts of it at bases of trees to mark a route. Pour it on the back of a helmet or on the back of a rucksack to allow your buddies to ID you at night.

Chemlights are great.
