Osama, you're wrong. The M240B is mounted on humvees throught the middle east and yes, some have the 25mm, but that's usually not mounted on the same thing. Those are mounted on top of the larger vehicles. Please don't come in here and tell me how to do my job and I won't tell you have to do your job. It's called a mounted weapon. And no one likes someone coming in acting like they know it all. You just look like a Richard. (you'll figure it out)
