To most this may look like a fireworks display but to war hardened vets this will bring back memories they may not want.
Trench warfare is a TOUGH game and not for the faint at heart.
World War I (WWI or WW1), also known as the First World War, was a global war centered in Europe that began on 28 July 1914 and lasted until 11 November 1918. From the time of its occurrence until the approach of World War II, it was called simply the World War or the Great War, and thereafter the First World War or World War I. In America, it was initially called the European War. More than 9 million combatants were killed; a casualty rate exacerbated by the belligerents’ technological and industrial sophistication, and tactical stalemate. It was one of the deadliest conflicts in history, paving the way for major political changes, including revolutions in many of the nations involved.
The war drew in all the world’s economic great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and the Russian Empire) and the Central Powers of Germany and Austria-Hungary. Although Italy had also been a member of the Triple Alliance alongside Germany and Austria-Hungary, it did not join the Central Powers, as Austria-Hungary had taken the offensive against the terms of the alliance. These alliances were reorganized and expanded as more nations entered the war: Italy, Japan and the United States joined the Allies, and the Ottoman Empire and Bulgaria the Central Powers. Ultimately, more than 70 million military personnel, including 60 million Europeans, were mobilized in one of the largest wars in history.[SOURCE](http://en.wikipedia.org/wiki/World_War_I)
