First, do as I say and not as I do... if you can be with your loved ones and dig in, do it. Clearing a house is risky business, even with a team of trained professionals. Doing it on your own is very dangerous, no matter how well you know your house or how many times you've practiced doing it.
That said, I'm not going to ignore my own personality and pretend that I'd be able to just sit and wait. My action would depend fully on where the noise is coming from. If it is in the den or livinig room, I am going to do my impression of a Marine Corps rifle squad on the offensive. If it is in the center of the house it gets too dangerous due to a room with 2 doors and the possibility of having a BG appear behind me in an already cleared area. If the BG is all the way in the back of the house in the laundry room I can get to him before he has the opportunity to sneak around behind me, and I would do so. Everyone is correct that stuff isn't worth dying over. However, if you enter my home when it is logical to believe that my wife and I are at home, I must assume you attend to do one of us great bodily harm. It isn't hard to guess where we are, so there is no great advantage to waiting for the BG to get there. There is no cover in the bedroom, though there are multiple areas of concealment. So if possible I'm going to meet the person that wants to hurt me on my own terms and do so with violence of action and movement.
I would send my wife to my daughters' room, and I would seek out and destroy any enemy that has chosen to make my home their target. Burglary is one possible reason for somebody to come into my home, but it is not the only one. I will assume that anybody that is unlawfully in my home intends to do harm to my pregnant wife and daughters, and they will be killed.
I don't have an option. With the way my house is setup, I must 'stalk'. There's a bedroom on each side of the house and me just waiting in one room, leaves others in danger in the other room.
I too will also assume that if you're in my home, with a driveway filled with trucks and cars, you know somebody is home and have intentions to do more than just burglarize my residence.
Despite the dogs barking at the sound of a leaf falling from a tree, I've got into the habit of checking things out every time. I don't have the luxury of knowing which night they'll be right and I rather lose some sleep than my life or a loved one.
...to shoot at movement alone, without verification/identification of your target is foolhardy, and invites tragedy.
I have three kids 11 & under, my foremost job is to protect them. The only light on in the house at night is over my kitchen sink. I will be emerging from my room, into a pitch black hallway. They will have the light behind them, and no night vision, I wait, crouched behind cover of a linen closet. No warnings, I will fire. If I go down, it's very likely the whole family could. No warnings.
My people hunting days are long past. 9-1-1 and wait at the top of the stairs.
I can only relate what my father did alot of years ago. It was about 3:15 a.m. and I was a 12 year old and dead asleep when he came in my room and whispered to me that someone was trying to get in the side door of the house and I was to take the shotgun and stand in the hallway next to the kitchen with the gun pointed up until he said to shoot. And then he said if you have to shoot - don't shoot toward the end of the counter because that will be me. Needless to say I was shaking like Barney Fife but my father had a very cool head. He had the training during WWll and had landed at Normandy, made it across France, Belgium and Germany with the 1st. Infantry. Anyway, the guy finally gets the lock open and gets in and as he takes his first step up the stairs from the landing my father said "Come on in - we've been waiting for you". The house is completely dark and quiet. I swear the guy could hear my heart beating in my chest. Then my father said "walk up the steps and shuffle your feet across the kitchen floor and sit down at the dining room table. If you run, we shoot." The guy shuffled across the kitchen and sat down in the dining room table. And my father told the guy to put both hands flat on the table - he did. When my father turned on the lights the guy had eyes as big as silver dollars because he was about 3 feet from the intruder with a bayonet pointed at him. I called the police and they came and picked this guy up. One of the officers asked my dad "Why didn't you just shoot him?" My father said " That would make a hexx of a mess and my wife would not be happy". the officer laughed and they got to talking and found out they were in the same places in Europe and the officer was in the 29th. division next to my father. They became friends and talked often of where they were. The home invader never came back after running into a bayonet, shotgun, and the police all in one night. As i got older I asked him about that night and he said -"never give up your cover and concealment - make them make the noise. Remember walk softly and have overwelming fire power" I think it was good advice.
I don't care that much about stuff, that can all be replaced. My life, however, can not. I choose to wait for the intruders to come to me. However, I will have heavily stacked the odds in my favor.
I would grab my pistol and retreat to a more secure position where I have my long guns (a safe in my closet). In there, I have permanently stored a spare set of glasses, a cell phone, a flashlight, and a remote that can turn on lamps in every room in my house. This remote is important because I will be in my closet with the lights off. To get to me/us, the intruders will have to walk through a doorway (where they will cast a shadow) then make a right turn (where they will be lit up by the lamp). I will have advance warning and perfect sight on them to be able to identify the target. I will be hidden in the darkness, laying on my side on the ground (to present a small target), and aiming my weapon at the only entrance. I will only have to worry about covering 3 feet of doorway with my weapon.
My significant other will take cover behind the door of the safe while dialing the police. When the police get here, she will give the 911 dispatcher the keypad code to open the garage door. Inside the garage, there is a combination lockbox that contains a key to open all of the entry doors.
There are some other things I should do. I should hook my light switches into the remote also. I should create some better cover, maybe stacks of boxes filled with phone books, or maybe stack a bunch of boxes of water bottles that double as emergency rations. Also, I should create a good backstop. In case I need to shoot, I don't want to shoot up my neighbor's house. A bookcase with plenty of books could probably fill that role.
i would get up grab my glock 23 and 800 lumen flashlight out of my night stand to my right, quietly wake my fiance and have her get our daughter (she sleeps with us) and get them into a corner we have picked out. wait for the intruder to get to the doorway light up my flashlight aim and let a few shots off till they are down and then call cops. its either them or my family and i and i wont take chances waiting it out for cops to come
