Right, because the military is the worst possible place to learn about the military. I'm better asking Richard Jewel about 2 man tactics than I am reading a military TM, which provides the history and theory as well as the tactics.
Just like your stupid ass bayonet claim, it's fucking wrong. The US Military does not have any serrations on their weapons because of Geneva conventions. It can not be used as a multipurpose tool, and has not been issued as a multipurpose tool for that exact reason. If you need to saw rope, you have to use an entrenching tool.
Contrary to your pathetic attempt at an ad hominem, the source is usually the best way to get information. Not always, but military doctrine and principles are very well documented and available to every soldier that wants to go read. Those same books are not always available to the public, so your Wiki page != US Military Libraries.
Lastly, before you go another round of pathetic fallacy, learn what "one of many" means and then reread the post.
