1st MAW here, sounds like fun.
Ya need a pretty long range for some of the big guns.. They can reach out and touch things 20 miles away these days and more with some tuneable ordnance..
Went one time to a Saturday AM live fire of a TOW Missile Company practice.
People, civilians and brass, were everywhere.
Everything went fine as one after another jeep mounted squads pulled up to the firing line and always hit the targets which were old tanks about a 1000 yards down range.
Then one squad fired and the wire broke that guides the missile and it went spiraling out of control.
People all over were hitting the deck, hiding behind cars or whatever they could find.
I remember hiding behind my car and thinking, “What the hell? This is a Pinto. If it hits I’m toast anyways!”................
