Really a modern day vicious instrument based on a medieval model...the mace. A good choice of weapon, when dealing with the confines of a trench. Rather ironic that trench warfare of WW 1 produced different pieces of protective gear (helmets) and offensive weapons based on medieval examples. In reality there are only so many ways to protect the vital parts of the body and more ways to kill the enemy. I would leave further comment to those of our members who have actually experienced combat.
