in a way, this seems impractical
i didnt watch the entire video mind you
how much does it cost? i doubt its cheap
like xant said, snipers will still need to be able to use a traditional rifle. that thing will break, snipers have access to various electronics to take most of the math out for shooting those long distances, but they are still taught how to do it all on just on pen&paper.
does that system only work with that particular weapon? can it work on a moving target?
while im no soldier, and have never seen combat, i doubt that the standard infantry are engaged in such long distances that this thing is designed for, so, why the hell would they need it?
meh, i just dont see the point, takes the fun out of practicing and improving your skills, in my eyes
