World War I was fought with new technology. Battles were waged by air, land, and sea. Destructive weapons such as mustard gas and machine guns added to the horrors of trench warfare. What effect did this technology have on World War I?

The use of technology during WWI change the face of the battle. Machine funs could wipe out an entire line of people. There was no need to march in line and fire at each other anymore. This led to massive slaughter and rose the number of deaths. Machine guns, tanks, flamethrowers, poison gas, trace bullets, interrupter gear, and other technology was invented. Overall the war could have been much longer if there weren't any of these new technologies.

A more effective way of killing people. Not only in killing, but killing in greater quantity and depleting the opposing faction's manpower far more quickly than ancient warfare could provide.
