1. you can put a suppressor on a 155mm howitzer too, which Germany produced for the M109G “Paladin”! The U.S. Army claims to have suppressors for both the 105mm and 120mm guns! But given their size is highly unlikely they’ll ever be used! The Dillon M134D 7.62x51mm NATO Minigun by itself without suppressor produces ~170-decibels of sound! With suppressor the noise reduction only amounts to ~155-decibels of sound, comparable to a unsuppressed 12-gauge shotgun! So unless subsonic 7.62x51mm NATO ammunition is being used, suppressing a Minigun using regular combat load ammunition doesn’t solve anything…

   • You said, “suppressing a Minigun using regular combat load ammunition doesn’t solve anything….”

     It solve plenty. Didn’t you even watch the video? He explains clearly, several times, many times, that the purpose of suppressing the minigun is to lessen the overpressure to prevent TBI (traumatic brain injury) as well as permanent hearing damage to the helicopter door gunners, pilots, and other helicopter crew exposed to the minigun. I’d say that preventing TBI and permanent hearing loss is a huge accomplishment.

     • And the helicopter engine of the helicopter you’re flying in! How do you “suppress” the noise of the helicopters turbo shaft engine producing ~100-decibels worth of sound! To use subsonic ammunition means the helicopter or light boat has to get closer to possible threat, because the subsonic ammunition uses nearly half the propellant load that normal ammunition loads use…

2. I think that’s the Marine Corp MADIS system at that timestamp.

3. That looks like the MADIS system the US Marine Corp has.

4. And there is hearing protection for the crew.

   We need to provide hearing for all who work in loud environment.
