Bayonet's where not knew to WWI but played an important role. Bayonets were mainly used in close quarter combat in trench battles. This pin shows a german soldier with his fixed bayonet ready for battle.
Looked up Samurai soldiers - the costuming looks pretty intricate and intimidating to paint. I could see us making something more like this much easier and cutting out the face. Also, without the info boxes, that will all be on the info poster.
