Smoke bombs can be a lifesaver when you are out in the field. They can help people find you or keep you hidden. Because of that, it is essential that you add a few to your bag.
Help People Find You
If you are with a group and you get lost, you can use a smoke bomb to show others were you are. Then, they can pick you up.
You can also use a smoke bomb to mask your movements. For instance, if you need to cross an area, you can throw out a smoke bomb and then run behind the cover of the smoke. People will not be able to detect you so you can get to safety. You can also use the cover of the smoke bomb if you need to rescue an injured member of your group.
Practice using smoke bombs before you go out in survival situation. That way, you will be ready to use them when necessary.
