NGAI and Major John
They put out a monthly newsletter / newspaper and what did I find in it when I flipped through today; the photo on the left here.
I believe this was the night fire portion of what they described as the .50 caliber machine gun. I can't tell from the photo if it is MJ's nemesis, Ma Deuce or some new fangled replacement. I never had the opportunity to fire the M2 so I'm not that familiar with it.
This went with a nice little article about the unit and their deployment. I'll be sending that to MJ by email.
