When travelling, working from a vehicle or in a hostile environment it makes sense to keep all your important and essential equipment in a bug out bag. From a tactical point of view, if you are attacked, ambushed or involved in an emergency situation and have to evacuate you will want to have any confidential information, emergency and survival equipment with you.
You never want to leave your essential equipment in an unattended vehicle, hotel room or non-secure location. For example, if the vehicle is stolen you lose your kit, which could be embarrassing to say the least especially where weapons and confidential information is concerned.
What you carry in your bug out bag will vary greatly depending where you are and what you are doing. For example, what you need in an urban environment will be different from what you could need in a very rural environment. What I have listed here is just a guide to what you may need, you need to keep things real and not include gear that you will never use, remember if things go wrong and you have to run you don’t want a bag weighing 100 lbs. on your back.
