This coming from a 13F who has worked with the guns. It is hard work. I have been down on the line humpin rounds with the crew, it is hard work. Takes a lot of strength, determination, and attention to detail. With "forgetting the powder", that is not cool. I was on an OP (Observation Point) registering the guns, and cannon crew didn't load the correct charge. The Guns were firing almost directly from behind us to right in front of us, Angle T was only 0020 mils. I will never forget having a 155mm HE round land 300 meters away. Not cool at all. I can only imagine what the Iraqi's felt when they landed 3 meters away.
BTW, quick info. In artillery, a circle is divided up into 6,400 parts, called mils. This is more than the standard 360 degrees in a circle. We use mils because it is more accurate. Also, Angle T is the measure of the smallest interrior angle formed by the Gun Target Line (the line from the guns to, through, and beyond the target) and the Observer Target Line (line from the Observer of the rounds to, through, and beyond the target).
