Describe the nature of trench warfare and the impact of the new weapons used in World War I.

Can someone help :( ?

The new weapons in WW1 made a huge impact. The Allied Powers didn’t know what to expect. Not only did they have advanced fire arms but Central Powers dropped gasses that could hurt their eyes, lungs and etc. The impact of the new weapons were devastating and were not expected.

When is this due and what grade are you in?
