suicide
You've learned a lot about the trenches, so you can imagine why soldiers would kill themselves. They would stick their heads out of the trenches in hope that they would be shot or they would shoot themselves or kill themselves in any other way.
punishments
Cowards or deserters, if they were caught, were severely punished. They would either be shot, or they would be chained to the wheel of an artillery gun for two hours a day up to 21 days!
other
Soldiers slept in funkhole- little dugouts on the side of the trench. Also, soldiers held heavy packs: they were 60-77 pounds! The packs held water, food, ammo, a shovel, a gasmask, a coat, spare boots, wire clippers, hand grenades and personal belongings.
