In a Q&A video a month or two back, I was asked what modern rifle I thought would be best for a soldier in WWI trench warfare. My answer was an AR-15, and I got a lot of people asking why. Well, because the AR is a more reliable rifle in really bad mud than the AK.

What I couldn't show at the time, but can now, is some video of both the AR and AK being subjected to a stupid amount of mud...
