Howitzer

noun

1. A cannon that combines certain characteristics of guns and mortars. The howitzer delivers projectiles with medium velocities, by either low or high trajectories.
2. Normally a cannon with a tube length of 20 to 30 calibers; however, the tube length can exceed 30 calibers and still be considered a howitzer when the high angle fire zoning solution permits range overlap between charges
3. A powerfully hit shot.
