martial arts in army is basically autism why would i use my hands when i have a machine gun :d
Cuz this is combat system not a martial art. BIG DIFFERENCE YA KNOW
Ok so to rephrase, why would he use a hand to hand combat system when he has a machine gun :p
Anyways to answer your op, Krav Maga on and off for a few years. It was okay. Some instructors had a tough time answering technical questions on the legality of self defense (big red flag). From a technical standpoint, what turned me away from it in the end was the fact that they were teaching "fighting" and not really self defense. Also the techniques they taught members of the public were watered down from what you see Israeli commandos doing in documentaries. DT LEO/EMS was much more useful but requires a certain level of maturity to use, so I can understand why they were hesitant to teach it to members of the public. LEO/EMS are held to a higher standard than the public with regards to use of force and they have a different job to do than the average person caught up in an altercation, so they taught us different stuff than what the "civilians" were learning. Was it engaging and did I learn a lot? Yes. Did it turn me into Jason Bourne? Hell no, that shit's reserved for special forces types. Short of finding a veteran commando to teach me a few pointers, I doubt I'd find that type of material you hear Mossad or whatever using being taught in a school/dojo/etc. I can't speak for everyone, just from my experiences, but that was my takeaway from the whole thing.
tl;dr martial arts for self defense are overrated, my .38 works just fine in its stead and modern wheel guns are notoriously reliable and easy to use. I might draw a lot of hate for my opinion on it but there it is
