I got to fire the MG42 when I was stationed in Germany during Desert Storm. It is nothing short of impressive. The amount of suppressive fire it can lay down is remarkable, as long as it can keep being fed. Our tactics against it during WWII revolved around attacking the emplacement during barrel changes, which were fairly frequent, but could be quickly done. The Germans countered it by pairing the guns whenever possible so one was always able to support the other.
The video showed it being fired from the tripod, which made for a very steady platform, but it was also frequently used from a bipod, like the older, smaller, and slower firing MG34. That's how I got to shoot it, prone with the bipod sandbagged to help stabilize it.
