I"m sorry but I have to throw the BS flag here semi_problamatic. First off bird shot and slug ammunition is unauthorized ammo heck it's not even military issue. Using it is a good way to get yourself standing tall in front of the man. Being that I was an MLARM intstructor (since your probably with 4/10 I'm sure you know what MLARM is) breaching with a shotgun is quick, and causes way less collateral damage than either a linear flex charge or a water impulse. Using those are much slower than breaching with a shotgun, as you have to pull security as the breacher attaches either to the breach point. Then the stack has to move away from the blast radius. With a shotgun you don't have to do either.

Using rubber ammo of any type on vehicles is just down right foolish and is a good way to cause bad things to happen quick. That stuff is issued for crowd control and nothing more. The issued mossberg with the pistol grip is not a good weapon to rely upon for going into a *known* hotspot as accuracy is horrible past about 15 yards. The intended purpose of the pistol grip is to keep OAL length down so it's out of the way of your primary fighting weapon which is your M4.
