M1911-
I deployed a canister in my garage once (I know, very stupid of me, long-story short, I wanted to get rid of some wildlife and firearms in the garage are out of the question, I won't bore folks with the story)... It didn't limit visibility too much. I do have enough gas-masks for myself, everybody who lives in my house, and the few oddball buddies who might show up when the townspeople begin turning into zombies (
) but I don't know if many/any of them are trained to fight with a gas-mask on.
I know I am not trained to fight with on one, not formally. The most I've ever done was wear one around for an hour, with my combat load and gear, just to get a feel for it. As I'm sure you either know or could guess, it is damn hot and uncomfortable in that thing.
In such close quarters, how much could it possibly impact my ability to identify and hit a target? Remember, we're talking a matter of 10-20 feet away (maximum distance).
Also, as far as training to fight in a CS rich environment, where would I go for this (short of the US military) where I could obtain such training, legally, as a civilian?
Even still, if it came to it today and I had to mask up, have my dad mask up, and deploy a canister. Wouldn't we be at an advantage over the attackers who wouldn't even have gas-masks, let alone have even so much as a basic idea as to how to handle the situation?
For now though, I'm just going to rely on situational awareness, observing my animals for any odd behavior, and my doors/windows, to provide the few seconds of time I need to get ready to repulse/blunt any attack.
Home invaders most certainly will have the initiative, since they decide when they are going to attack. The key to any defense (as I see it and as many military leaders in history seemed to see it) is that you blunt the first attack as quickly as possible and take the fight to the enemy. You want to seize the initiative away from them, and take the fight to them. But, never underestimate the effectiveness of letting them blunder themselves into your defenses. Just when they think you're on the run, they run smack into your concealed 88mm anti-armor positions (well maybe in 1942 North Africa, not in my house, but you get the idea).
I want to equip myself as soon as possible when the door (or window) comes crashing in. I always have a pistol on my person and usually a rifle by my side. Being equipped means at the least being able to oppose them and offer them lethal resistance. Ideally it means putting my armor on and obtaining a long-gun for my father as well (he always has at least a pistol), and even better, also having him armor up.
If somebody just burst into my house right now, it wouldn't take me but a few seconds to have a magazine emptied into their body/head, or to have my dad give them the same. If there was a gang or I had some sort of 20-30 second notice, I'd have my main rifle ready, a backup laid out nearby, and I'd be wearing my armor, helmet, and I'd be in a good position. Hell, I might even be able to get that done in 15 seconds.
I'm going to think on what you said and probably will discount CS as a tool to use against home invaders. However, what do you think about dummy frag grenades? If I keep one near my bed, I have a perfect angle to toss one out into the hallway and down the stairs. If bad guys were coming up the stairs, do you think the sudden sight of a hand grenade (they wouldn't immediately know it was a dummy) landing next to them would cause them to run and dive for cover, buying me at least 5-10 seconds?
