Hint: It looks like a big explosion.
Though the M60 machine gun has more or less been phased out in favor of the M240B, it is not for a lack of effectiveness. Both weapons fire a 7.62 mm NATO round which is highly effective against unarmored vehicles like technicals or civilian vehicles. But what you will see in the following video is that the M60 is perhaps most effective against a pickup truck packed with more than 100 pounds of USA Chemical Supply exploding targets.
It makes a big boom. There’s another video on the next page from a slightly different angle.
Shot from the other side of the Durango, still a great big boom.
