MY COMMENT:
(VIDEO WAS SPONSORED BY A COMPANY SELLING SUCH GEAR.)
Non-vet civilians will never (legitimately) be running fire-and-maneuver calling for all that gear. In a real and legitimate Militia situation they will be fire support, set-position defense, and logistics. A simple mag pack is quite sufficient. Beyond that, anything much more than a pack or such for evacuating in a disaster is a hobby at best and a delusion at worst.
I'm a vet. I served in a combat zone. I have a vest, CamelBak, and pack which I acquired during my service, and keep solely to be able to quickly bug out of town in a disaster, be it on foot or in an official evac vehicle with limited space.
To non-vet LARPers: Buy what you want. Support this guy's sponsor. But keep in mind you are NOT the same as veterans. You lack the training and DISCIPLINE that veterans had drilled into them. If/when SHTF, you can serve a purpose, but you aren't the same.
