Laconic / World War I
aka: World War One

The first modern war with machine-guns, gas, airplanes and a plethora of similarly nasty things. Eventually ended when one side suddenly gained a huge manpower and industrial advantage just as it realized armoured motor-vehicles could go over the trenches.

Alternative Title(s): World War One
