kceaton1 says... This is obviously a very great skill and at the same time it has its faults. It's also obvious to anyone with common sense that he IS a "trick" shooter. I mean almost every demonstration in the video IS a "trick" shot of some kind. Would any of these things come in handy in war... Certainly, many of those "tricks" would put him at an extreme advantage--especially if he could do this extremely well on horseback (and you must be a GOOD horseback rider, motorcycles don't count--a horse is a whole different story; especially if you plan to do some of the *feats* I'll mention below, while in combat). He would be even better if he had mastery over the shorter bow(s) he uses in this and also a longbow for long targets and heavily armored enemies. As for him penetrating chainmail, that is a good question and I do believe he could quite possibly end up penetrating the chainmail in some situations while (possibly still getting through the chainmail) being stopped in others (he shows being able to penetrate mail with an under armor of some type, but we don't get a lot of details about that situation to be honest). It depends on how his bow is made, the string it has, the type of arrow he is using (or the tip, to be honest), and his draw strength (along with this is range). On the chainmail side it depends on what type of chainmail the enemy is using and then whether they have an under armor of some kind--and again, range. The problem in this video--except for a few shots--is that he does shoot very close in many of the cases; within 30-20 feet. In a close combat experience--which wasn't necessarily unusual for archers in the past (especially as I mentioned mounted ones--of course you'd be nuts to not be mounted at these ranges--or at the least be a swordsman as well...which was even more rare) he would terrorize opponents... Unless they are wearing plate or other heavy types of armors, then he is in a bit of trouble. But if he really does have great accuracy, then even many of these armors types wouldn't necessarily help you--and could eventually lead to your own death. I say we give this some time and see if Lars gives us more answers (like "records", competition, types of bows and arrows, chainmail used, etc...).
