"In the taxonomies of artillery pieces used by European (and European-style) armies in the 17th to 20th centuries, the howitzer stood between the "cannon" (characterized by a longer barrel, larger propelling charges, smaller shells, higher velocities, and flatter trajectories) and the "mortar" (which was meant to fire at even higher angles of ascent and descent). Howitzers, like other artillery equipment, are usually organized in groups called batteries." - (en.wikipedia.org 01.03.2020)
