The modern mortar is a muzzle-loaded weapon and relatively simple to operate. Thinset is a mortar made of Portland cement, silica sand, and moisture-retaining agents. In the conditions of trench warfare, there was a great need for a versatile and easily portable weapon that could be manned by troops under cover in the trenches. As a result, they developed a short-barreled rifled muzzle-loading mortar called the Minenwerfer. These answered as Coehorns, and shells were successfully thrown from them into the trenches of the enemy".[11].
