Bigger Guns, Higher Death Rates

The trailer of Gallipoli, the 2005 movie featuring the actual scenarios of World War I as much as possible, seems to repeat one occurance quite a few times: an explosion. Around 5 explosions occur in the course of the one minute and fifty second video. This goes to show that one obviously significant factor in the never-before-seen death rate during the Great War would be the great weapons used within it. Technology was advancign and being put to good use. Between the newfound technology and the trench warfare, [also shown in the trailer,] it is hardly a question at all as to why so many more deaths occured during this war.
