How do guns, howitzers, and mortars differ in their firing trajectories?

In military artillery, weapons are categorized by their design and the specific firing trajectories they employ:

  • Guns: These are cannon designed specifically to fire projectiles along a flat trajectory.1
  • Howitzers: These are shorter pieces engineered to throw explosive shells in an arcing trajectory.1
  • Mortars: These are very short weapons designed for high-trajectory fire, typically at elevations greater than 45 degrees. This high-angle capability allows them to drop bombs into protected areas, such as enemy trenches.12

While guns prioritize a direct, flat path, howitzers and mortars utilize varying degrees of curved trajectories to reach targets that may be obscured or shielded from direct fire.12
