What it is Filled

A cannon is a member of a class of artillery that fires projectiles using propellant at a low or flat trajectory, including historical muzzle-loading pieces of bronze or iron and later breech-loading artillery; cannons are treated here as historical, museum and technical objects, including ceremonial uses, without operational detail.

Why it exists Filled

Let an agent explain the history and general technology of cannons, describe museum pieces and ceremonial uses, support heritage and identification questions, and decline operational or manufacturing detail.
