Well, if we all suck so bad, why don’t you join up and show us how it’s done?
I did about 23 years ago. My MOS was on the deck with a weapon in the boonies. I got to play in 29 palms and the fun streets of Carlsbad, even played in the beautiful wetlands off Sneads Ferry and Chad"licks" Bay. Walked along the quiet streets of Parris......... Island and even went on romantic cruises to Indonesia, Nicaraugua, Lebanon.
If I was told to fire on American citizens that were threatening me and my brothers by my CO I'd assess the threat and lay down coordinated fields of fire with flanking maneurvuers until the threat was destroyed, objective taken and perimeter secure.
As for "how it's done"... just put your feet on the yellow footprints in the street and enjoy the ride brother.
