World War I, also known in its time as the "Great War" or the "War to End all Wars," was an unprecedented holocaust in terms of its sheer scale. Fought by men who hailed from all corners of the globe, it saw millions of soldiers do battle in brutal assaults of attrition which dragged on for months with little to no respite. Tens of millions of artillery shells and untold hundreds of millions of rifle and machine gun bullets were fired in a conflict that demonstrated man's capacity to kill each other on a heretofore unprecedented scale, and as always, such a war brought about technological innovation at a rate that made the boom of the Industrial Revolution seem stagnant.
The arms race before the war and the attempt to break the deadlock of the Western and Eastern Fronts by any means possible changed the face of battle in ways that would have previously been deemed unthinkable. Before 1914, flying machines were objects of public curiosity; the first flights of any account on rotor aircraft had been made less than 5 years before and were considered to be the province of daredevils and lunatics. By 1918, all the great powers were fielding squadrons of fighting aircraft armed with machine-guns and bombs, to say nothing of light reconnaissance planes. Tanks, a common feature on the battlefield by 1918, had not previously existed outside of the realm of science fiction stories written by authors like H.G. Wells. Machine guns had gone from being heavy, cumbersome pieces with elaborate water-cooling systems to single-man-portable, magazine-fed affairs like the Chauchat, the Lewis Gun and the M1918 BAR. To these grim innovations were added flamethrowers, hand grenades, zeppelins, observation balloons, poison gas, and other improvements or inventions that revolutionized the face of warfare.
These technological developments led to an imbalance. Before the introduction of the man-portable light machine gun (which took place in the second half of the war), not to mention tanks (which also joined the fight late in the game), defensive firepower vastly outweighed offensive capability. Massed batteries of artillery, emplaced heavy machine guns, barbed wire entanglements, and bewildering fortifications meant that ground could not be taken except at incredible cost. This led to the (somewhat unjustified) criticism famously leveled at the generals of World War I that their soldiers were "lions led by donkeys." Certainly, every army that fought in the Great War had its share of officers, at all levels of command, who were incompetent, unsuitable, foolish, or just plain stupid, but there were plenty of seasoned professionals who understood their job and did it well. The main problem facing commanders in the war was that there was such a bewildering array of new armaments, with such vast destructive potential, that previous military doctrines were virtually useless. Cavalry, which had been expected to play a major role both as reconnaissance and as "mounted infantry," operating in much the same way as airborne and mechanized troops would later to rapidly outflank enemy positions, quickly proved useless. Frontal infantry assaults were cut to shreds by enemy defensive fire, but there seemed to be no major alternative. Ground had to be taken, even if at great cost, and to do so, more destructive weapons were devised, tested and deployed.
As a result, World War I was the first truly industrial war, and it created a paradigm which reached its zenith with World War II and towards which virtually all equipment, innovation and training were dedicated throughout the Cold War and the remainder of the 20th century. To this day, modern warfare remains synonymous with tanks and mass infantry battles.
