Interesting Thread.
My plan is much like RKs, but has some more parts to it
My house was purchased with a home break-in scenario as a consideration. All sleeping areas are on second floor. Master bedroom has clear sight line of to stairway. One child still in the house, has bedroom next to master, 3 feet away from master br door.
Bump in the night drill is as follows. Upon alert, (dog, alarm, etc) wife and I make sure each is awake. I secure Glock and mag light, move to daughter's room and move her to master bedroom (she is instructed to remain in room until either of us get her). While doing so, wife makes 911 call and secures Scattergun Tech 870 from closet. I return with daughter, shut door, turn on bedroom light and all move both to master bath, which has clear sight line to bedroom door. (Contact maintained with LE dispatch throughout situation).
At this point wait. If intruder(s) is in house, he/she/they can have anything in it outside the master bedroom (that's what insurance is for!) If BG(s) comes thru bedroom door, I'm ready and prepared to engage. Upon arrival of LE, front door key on big hunter orange boat float key chain out the bathroom window to front lawn for LE folks. Further action depends on how LE folks want to proceed.
Too paranoid, Too cautious? Perhaps, but some key things to consider.
1. I have made the determination at this point in my life not to do any house clearing if I don't have to, and if allowed the option, will wait the situation out from a defensive position of my choosing. My thinking is also greatly influenced by a home invasion situation when I was 17. (Worked out OK, but upon much review as I've gotten older (I'm 50), was based on luck since my mom and I didn't have a clue!)
2. There is a plan, and we practice it, including communication between ourselves during the drill, redundent comms (cordless/cell phones), switching roles, and one parent options. (Ayoob's thoughts and recommendations had a great influence on the decision/planning process). Is the plan perfect? Nope, no plan survives first contact with BG/enemy. There are always variations/contingencies to consider/execute as the situation develops.
3. Having done actual, hostiles involved house clearing ops (military, not LE situations) I don't really want to ever do another, especially since I don't have access to the personnel/gear/weapons mix available in those ops. (teammates, NVGs & frag grenades are wonderful things!)
4. I know my limitations and would much rather leverage tactical and personal advantages, rather then mitigate weaknesses. (The older you get, the better you was!)
My considerations and decisions in this regard may not be yours, but this works for me.
Pretty verbose I know, but just my opinion. All comments encouraged and welcome!
