That's a Euro sog thing. Afaik its still not commonplace in most training, although fairly effective in slowing someone down the problem there is people can still shoot you when they aren't walking
Ahhhhh, that must have been what it was, and makes sense now why I couldn't remember where I got it nor find any supporting documentation. I've made the acquaintance of a number of SOG-types over the years, including a few Euro's.
People can, of course, shoot at you when they aren't standing, and there have been a number of incidents that have shown just how many bullets some people can eat - even in "critical" areas, and without being on drugs of any kind - and still keep going, however...
I
think the idea with this one is that you don't consider them "down for the count" at that point, so much as it's easy to quickly dump 5 rounds in an area that size - especially since the worst that happens is muzzle rise puts a few rounds in center mass - and while they are in the process of going down from one or more hits, you move in and either disarm them or issue follow-up shots as needed. Chances are high that they're not armored in that region and will "go down" if any one of those shots actually hits the hips, even if only for the moment it takes for you (or a squad mate) to close in and take control of them or their weapon. In theory, that group of shots is much easier to make quickly - especially as a reaction shot - with a minimum of fuss than trying to execute a Mozambique.
Still training for center mass accuracy when I'm at the range, but that's more about proper sight alignment and trigger control (and not ricocheting rounds off the floor of the range), but this seems to me a reasonable technique when only dealing with a single opponent at short range.
