This is ment more for after the outbreak is full throttle. There are many untold dangers of scavenging and salvaging things from "empty" houses.
First thing is you never truely know if they are empty. There are always the 2 legged walking, and the 2 legged shambling. You can't ignore the chance that there are some 4 legged ones that may have moved in as well.
Zombie survival guide and WWZ touched on urban combat a bit, so many blind corners, packed rooms. Zombies or trigger happy survivors can be anywhere. Ceiling, floor, hidden closets, behind furniture, prone behind/under shit. You never can tell, so ALWAYS go very very slowly. After a house is cleared, clear it again in reverse order. If the situation permits make sure you and your partners know where everyone is. Talking quietly if you have to. Just make sure you don't unload your double barreled zombie repellent in one of your friends.
Another thing to be wary of is traps and boobie traps. Treat every house like it's a meth lab. Watch for fishing wire, lumps in the carpet, anything that looks like it's been messed with and is out of the ordinary. If at ANY TIME you see something that looks odd, find another way in.
My personal recommendations:
Surround and check out a house thoroughly before approaching. If the situation permits, yell out to the house to see if anyone is inside. If no answer yell out that you intend to approach the house please don't shoot. When you are just outside the house, call into the house again/peak through windows. "Is there is anyone in the house? Is there anyone wounded? Trade?" "If anyone is at home, please say so I'd rather move on down the street than get shot!"
If at any point someone takes to shooting at you, it's time to move on to the next house. Don't even waste your time with suppressing fire.
If there are booby traps, move on to another home. If you think there are booby traps move on to another home. If needed leave a marker for booby traps in home.
Anyone plz add to topic
