Battlefield ready requires lots of 4 inch gauze , lots of elastic wrap---both from amazon.com
plentiful stop bleed powder for you and your friends
plentiful salves and or sprays for wound repair
sea weed sheets to cover the salve properly
pads for bad injuries
ALL that simple stuff, will be 100% gone---day 1 of any war for civilians
same with all the toys required to product your life-------even uncle sam says you should have a 1 year supply of food and ability to protect and keep it.
