That's what I kind of figured. Almost got suckered into serving in one of the glorified mortar platoons in the '60's.
That was in the early days of planning for the new army, the one they are designing for running around in modestly armored cars waging war in urban areas on citizens throwing rocks ala Palestine.
There is a video out there of a Davy Crockett being fired from a Jeep at Yucca Flats, Nevada. The launcher was at 45 degrees, ensuring maximum range.
The round was fired...the blinding flash followed...and the Jeep was picked up like a Matchbox toy car and tossed about a quarter mile before it bounced...yeah, I'd feel REAL comfy shooting that thing off...
