I've been in combat zones however never claimed to be in combat. This guy knows of what he talks about. You have to think about the unthinkable. I spent 5 years in the infantry, 16 in logistics. Your supply line is the most important thought. Think about it. If you can't resupply yourself, look at what you can carry, that's it. Also consider this, how far can I carry what I do have? Most folks don't asked themselves this question. However, when you've humped a ruck for a few miles you'll will wish you did.
