Thanks, Larry.
At that demonstration we didn't get to see the weapons up close...we were in bleachers and they were out front.
They did a "fire for effect" thing with the 81s and the 4.2s...quite a few rounds in the air at once.
The target was an old track of some kind WAY downrange...at least a thousand yards out.
They were puttin' some bad juju on that track!
