Use the catalog next time faggot, assuming this isn't bait. Lrn2weapon. Especially guns. Suck a dick if you have to. Parkour and self awareness best self defense. Shit like krav and military stuff is basically a crash course for if you don't have time to git gud, since if you lose your gun you're probably fucked. Incorporating dirty blows would be easier if you're good at something anyways. The drills could be good though. If systema is anything like aikido, it's probably shit. Technically there are parts of it that can work, but only against drunk shits who won't put up much, or during very specific situations, so it's no good unless as a supplement. Grappling is good one on one, but shit like judo might be usable if you git gud enough since it has muh standing takedowns. Groundwork stuff like BJJ can work one on one. In a group you're fucked. Any kind of grappling can get fucked if the dude has a knife or gun. Might be able to do dome of those crazy wrist lock self defense bullshit if you're already super close when he's reaching for something, I don't know. Wouldn't risk it though. Striking is striking. Be competent at one and you'll be ahead of wild haymaker retards. If the guy don't know shit about grappling or a striking art with kicks, than lowkicks are your friend. Boxing has good footwork and swaying to avoid punches. Muay thai is good, and it has really good synergy with judo because muh clinch. Tkd has kicks, probably shit on its own in da streetz. Kyo is cool, and will make you a tough sonuva bitch, who can take and dish out hella body blows while being used to no gloves, but in competition there are no head blows and they just kind of stand there and beat each other. FMA and similar are cool if you can carry a dumb stick with you. Knife arts are a thing but stabby stabby gets the job done. R8 my post /asp/, give me validation.
