What if your enemy also has poison gas? That is where gas masks will come in. The first gas masks were crude, sometimes just being cotton balls and stifling gags, but they slowly developed into the "tube" masks, comprised of two main parts.

Trench warfare is almost never over in under a day. It is often filled long periods of preparation and boredom, interrupted by the occasional outburst of fighting in the no man's land. Many soldiers are driven insane by the boredom. The secret? Keep yourself busy. Letters are useful, but many card games exist to blast away that boredom ("What").
