most ex-military become the modern day vikings ravage, pillage, steal your beer, burn your town, slaughter your children kind. these guys may hold a facade of good intentions guard duty they'll do it, perimeter sweep they are on it until you wake up and realize half your foods gone and your ammo boxes are empty. Don't fall for it folks keep a close eye on them. One way I found to tell the good from the bad is how they introduce themselves do they give you their rank and position? if so good that means they may still be in the military or what is left of it. What you have to understand is when society crumbles some people will rise up and help others while some will lose all morals and leave you to die in the middle of nowhere. Keep this stuff in mind and use common sense and keep your wits about you, if you survive find me I am on the east coast.
Not all ex-military are still the good guys
