I didn't say it was overwhelming, I'm saying the Viking analogy doesn't work well. There are roughly 20k volunteers in Ukraine total. I'm unsure of the exact nationality break down, the numbers flucuate obviously from the trickle of new people and the attrition of dead and wounded. Some do the 6 months and go home. Some stay. I think it counts as a multitude, YMMV. Last I checked there was about 800 Swedes there. Roughly same from Finland, I think about half that from Norway. I don't remember any Baltic numbers, would have to research more.
So, you think those norcs volunteered? We're talking fighting spirit right? And you're comparing Foreign Legionnaires to the 21st century's Asian blend of slave and serf? I admit being brainwashed can help on the battlefield, I just don't think it compares to what we're seeing from the Ukrainians themselves, or from allies who personally elect to put their lives on hold, risk their lives for zero necessity. With agency comes truth. Not a lot of that on the NK side. Those guys have different priorities, like 3 meals a day, all the porn they can fap to, and conducting themselves in a way that doesn't land mom and pop in a gulag.
The AFU turned the Kursk area into a mass NK gravesite, just sayin. Putin ran through his initial supply of NK meat, had to ask for more. While they are usually better shots and have better physical conditioning then russki mobiki, they're still being used as meat. To my knowledge no NK unit has developed a reputation for top notch ass kickers. On the Legionnaire side we've seen battle hardened Columbians as well as French, American, British, Canadian, Finnish and Aussie ex-SF absolutely mop the floor with the Russians, for years. As Ukraine has been so keen to adopt Western tactics and NATO standards a lot of these people have proven to be invaluable sources of experience and training. Hard to quantify that kind of contribution but I assure you it has been substantial.
