That video shows Hollywood bullshit...
Yeah dude, keep in mind those guys are not professionals in that art. For only 2:49 minutes they were allowed to demonstrate, they obviously learned to perform moves/stunts that would impress
mainstream public. Some of them were obviously way over the top. Like noone with a rifle would try to stab you with the barrel
In terms of Khridoli, here's some short info.
Khridoli's traditional Georgian martial arts dating back to antiquity. It part of the hand-to-hand training program of the SOF. They base their fighting techniques on Krav Maga and Khridoli. Khridoli is basicaly Sambo and Krav Maga combined, yet going further. It hardenes your body to the extremes and improves coordination in first place. Originating from ancient-middle age period wrestling systems of different Georgian regions, it show similarities to other martial arts, but is very unique in nevertheless not least because Khridoli back then, was purely about life or death. Due to constant threats of an invasion ( Georgia found it self surrounded by enemies for centuries ) people, in particular the "highlanders" ( Khevsurians ) thought themselves how to survive in case of war. Fighting numericaly superior opposition was common for a country like Georgia. Khridoli was aimed to learn attacking and defending with literaly
any sort of melee weapons/tools ( starting from regular cloth or hats, small finger pieces, knuckles, knifes, daggers, staffs, whips, axes, swords .... ( all weapons according to that period ). Today those are mostly used for public demonstrations by the Federation, yet however most of it applies to real combat situations with deadly efficiency. SOF approves.
For those who attend consequent life experience with Khridolo, theyy'll find themselves spending most time in mountainous areas and highlands in a is very traditional spiritual way.
