A trench mortar is a type of mortar specifically designed for use in trench warfare. It's a short-barreled, high-angle firing weapon used to lob projectiles into enemy trenches. Think of it as a compact, portable artillery piece ideal for confined spaces. Unlike larger artillery, trench mortars are easily moved and deployed within the trench system. They provided infantry with much-needed close-range fire support against entrenched enemies. Their steep trajectory was crucial for hitting targets within deep trenches.
