What type of combat characterized wwi?

Trench Warfare. Which often consisted of long dug out trenches, and opposing sides "going over the top" in an attempt to overwhelm the other forces. This led to the phrase "No mans land", the space in between trenches where men would be killed almost immediately if they were made to go. Other characteristics of WW1 combat would be the massive technological advancements that came with the industrial revolution, and weaponized   chemicals making a debut to the world through WW1.
