I have seen varied results with single hits to the vitals out to the 300-350 meter distance, not just with green tip. These results varied from "rag doll" to the guy dropping and flopping around for a while. The only constants I personally saw under these conditions:1- A good hit to the vitals at these longer distances (100- 350-ish) was either immediately fatal, or very quickly took the enemy out of the fight, in the sense that he was more concerned with the leakage, onset of shock, difficulty breathing, etc. than returning fire at us (where we were a respectable distance away) with his AK, PKM, RPG, or whatever he happened to have. I also never saw anyone take a solid hit to the vitals and "shake it off" or "just keep coming like nothing happened". 2- a hit somewhere other than the vitals with anything is likely going to be crap. I ran past a man with his leg hanging on by a strip of skin (essentially amputated) by a 7.62 round from a M240 MG trying to escape by crawling away, and doing a pretty good job of it. Of course, adults in these countries typically have the muscle mass of a small child in the US, but that's not the point- his leg was still coming off. If he was capable of doing that, then he was capable of firing his AK (which he had abandoned down the block where he was hit). The reason he didn't do it was that he CHOSE not to. I also saw one that got hit in the butt cheek by a 5.56 that exited out of the front through his intestines continue to fight for a while. As with all things, shot placement is king.
