How many people does it take to maintain and operate those weapons systems?
@Smokin Joe I know very little about modern,or even 1960's artillery pieces. What I DO know is that the typical high school graduate of today is a lot less educated than the typical high school graduate of the 60's.
I also know that the one thing high school kids all over the world can do now is play video games,and I SUSPECT they will have very little trouble operating the modern field piece because it is a hell of lot easier to "dial in" a target in the digital world of today than in the "operate the elevation crank and look up the chart to see how many powder bags we have to throw in to hit a target in "x grid". I would be shocked if the modern arty grunts have to do much more than punch in the grid codes,and the arty computer will tell them how many power bags to use and what degree of elevation. Hell,I doubt they even have to crank in any elevation these days. The computer probably does it for them.
It's kind of like driving a car with an automatic transmission when all you have driven are standard transmission cars. It will take some getting used to and a little instruction,but it ain't rocket science.
Now,I have no doubt the commissioned cannon cockers are MUCH more educated on the systems than the "field hands" are that actually shoot the guns,but it can't be all that complicated to just operate the damn things. Especially not compared to the old "pre-computer" days.
Maybe some modern day "Red Leg" can step into this conversation and set us all straight with actual knowledge?
