I said it in first post, but I’ll say it again. A mortar would be so much more easier then building a machine gun. And second who said anything about trench warfare? I was thinking something along a small mobile mortar. Don’t get me wrong. The machine gun and mortars have their own roles to play. I’m just saying instead of building a weapon with many moving parts, with long build times. Is not as cost effective as a tube of metal would. So if you add all that. You also have a better chance for craftsman to build them instead of having everything done by witches. And lastly their both design to defend against mass attacks.
