Awwwwhellsbells! I was a scout...I radioed FDC of the target I wanted hit, and they gave my info to the gun line. It could be the lay of the gun, survey/meteorology error, or a windage/ elevation error.
FReeper oh8eleven would have a better grip on what could have gone wrong.
My answer: Army Artillery!
BTW....an artillery “projectile” is indeed a shell. That shell encases a timer/fuse, high explosives, white phosphorus, flares with chutes ( illumination ) mines, hell all kinds of crap...Google it...too much to mention, and every damned shell is funner than hell to shoot! Teeth rattlin’, head duckin’, fun.
Good evening, OO!
Sorry My bad. I’ve already posted several goggle links and a pic further down thread.
