How Did The Advancement Of Weapons Technology Prior To World War One

The fact that there has been significant evolution in infantry tactics during the past century is taken for granted. Also, it is well documented that the predominant advancements in tactics took place between 1914 and 1918, during World War One, rooted within the German army. However, the cause and effect that initiated this rapid evolution is somewhat unclear. Was this advancement solely due to the inspiration of one or more German commanders of the time? Was this advancement in tactics a Revolution in Military Affairs? Or, was this merely an evolution in tactics resulting from advancements in fire power due to technology improvements in infantry weapons such as the machine gun, infantry rifle, field artillery, etc.
Prior to World War I the German army had studied and toyed with new tactics off and on. By 1914 they were still practicing traditional tactics against the Allies. The use of these tactics against the massive destructive capability of modern weapons available to both sides at the start of the war caused enormous numbers of casualties. The German army, in comparison to the Allies, was limited in numbers of soldiers and material and could not afford to continue to keep up with the high attrition rate. Necessity being the mother of invention, the Germans acted aggressively in finding a way to defeat the advanced firepower that emerged during the war. Through experimentation and training they developed the famous “Storm Troops” that momentarily broke the deadlock near the end of the war. After World War I these new tactics were taken up by other forces around the world and eventually led to German Blitzkrieg tactics of World War Two.
