That is awesome! You can see the dust and smoke coming out of the connecting tunnel entrances.
I missed what you pointed out when I first posted that video on my Android phone.
I sent the video out to family members and friends, and they got back with what you noted.
So I ran it on my Ace Chromebook 15, and like you noted, It is awesome.
A friend was AF security and his Nam tours were in Laos protecting our planes, supplies, pilots and other guys who kept our planes flying and bombing.
He went into the VC tunnels around our air bases to take out Charlie. This weapon would have been great for him and his guys.
Yes, amazing destructive power.
A MOAB would be a bit too much for the Tunnel Rats, however. LOL
(I was a Tunnel Rat for only two weeks. That was enough thank God).
