Weapons had gotten really good at statically hitting targets, but weren't mobile enough to further support an advance. All you could do was break the first line with it, but by the time you got to the second line the defenders had rallied and pushed you back. The blasted mud and craters between the frontlines hindered moving up your artillery, tanks were in development, but too slow yet, planes were unfit for anything but spotting and the war effort ate most of the resources so there was little left for the development of new technologies. The only option left was to hope that one of your charges would manage to rupture the enemy line and open up space to bring in more troops and start disrupting supply lines. That lucky break always seemed just one more hard push away...
