“If you’re planning on doing community security here’s a few tips.
If you’re planning on standing at an entrance I’d start buying and filling sandbags or have something else that’ll stop bullets. Standing out in the open is good but you want to make sure to have cover. Cover is something that stops bullets. Make sure it’s big enough to hide behind, none of us are as small as we once were. The engine block of a vehicle will stop most rounds, but the rest of the vehicle can be easily penetrated. Also remember the height of the vehicle, bullets can go underneath or bounce off the ground.
Have multiple fire extinguishers and other supplies, you might be out there a while.
Make sure you have communication with others in case you need backup. Radio, cell phones, flares it doesn’t matter as long as those that need to know know.
Have a decent first aid kit with plenty of tourniquets, medical might take a while. If you don’t have tourniquets watch videos of how to make and use them. You want them high and tight, and then tighten some more.
If your a group, make sure everyone has plenty of ammo. Random neighbor with 5 shotgun rounds isn’t going to be useful if he uses them in the first 5 seconds and misses everything.
If you have time, put out distance markers in relation to where you’re defending , that way everyone knows how far **** is. Plants, trees, street signs, whatever works.
Consider less than lethal options. A paintball gun with cranked up velocity can be a good deterrent that gives you better range and allows you to have something other than lethal options. Check the neighbors 14 year old kid, he probably has one.”
