People ought to remember that this war made the US a world power. Overnight a world order based on hereditary crowned head rule went by the wayside, and war went from being
a glorious romp on horseback to a muddy heartbreaking slaughter.
Its sad to see the archival film of Tommies and doughboys headed for the front knowing that a good percentage would never see home or even have a known burial place.
Please read more history. War was only a "glorious romp on horseback" to the ruling class. The lowly peasents were placed in the infantry and given inferior weapons, weapons which were used only against other peasents. The cavalry were the elite, the sons of nobles and lesser nobles who, most likely, bought their commissions and had no training in how to run an army and learned through OJT.
When firearms were invented the knights(if you wish to call them that)screamed about them being devils weapons, they were appalled that the lowly foot soldier could now bring them down,that wasn't supposed to happen, only other cavalry(and by default other nobles)were supposed to be able to bring weapons to bear agaisnt them.
The gun control movement has its roots in the distant pass where nobles tried to outlaw firearms for warfare, especially rifles.
Rifles were especially evil because they were accurate and killed more officers. The church banned them(at the insistence of the nobles)because demons hid in the rifling and then grabbed the ball on its way out of the barrel and guided it to it's target.
They proved this by making silver balls(no risque jokes please!)and cutting a cross into it and of course accuracy was poor because silver won't hold rifling as well as lead and the cross cut into it distorted the ball also.
War has always been a slaughter for the foot soldiers. Firearms, machine guns in particular, evened the odds so that every one was equally in danger. Machine guns, and the old fashioned tactics used in WWI, caused a casualty rate that was unheard of before that.
