I, ME, I am not "connecting" them to prone/crouch. All of the malfunctions you listed are mechanical causes. Even though you didn't actually list them correctly. (A misfire isn't caused by having the weapon on safe, that is another human error. Nonetheless, I can agree in principal with your comments. However, there are additional reasons that
can set these things in motion. Poor weapon handling, without going into exact specifics, is a primary cause. Especially with handguns. Poor, or weak grip accounts for more malfunctions that I have seen, as opposed to a true mechanical problem. Try repeatedly firing a rifle without placing the buttstock into your shoulder. It may not happen every time, but chances are, you will probably see a stovepipe type malfunction, at a minimum. Weapons aren't specifically designed to account for recoil in thin air, with no support.
As you can see malfunctions are mostly caused by bad equipment and human mistakes
Right. Which leads to my previous comments, which would include operator error. As described above, when is the most frequent time that you would remove a weapon from your shoulder to fire, and move into another position? Crouch, and prone. Soldiers are
supposed to exercise good fire discipline. Therefore, you probably wouldn't be firing while moving in and out of the prone position, and if you did, it could conceivably lead to problems. Agreed, it's a stretch, and it's just a game discussion, but that's where I was coming from.
Who said anything about dirt? Unless you are referring to my sarcastic comments about weapons cleaning, which was only meant to show, once again, that in real life, you can't go through 837 firefights without weapons maintenance. That's a fact. And dirty weapons lead to malfunctions. How else would you find a bad extractor or chipped rails, or any number of other things that might be beginning to fail on your weapon?
