The main idea is that this weapon type combines fast projectiles with a wide range of firing angles and good accuracy under indirect-fire control. A howitzer fires rounds at high muzzle velocity and can elevate the barrel from near-horizontal to very steep angles, giving both long-range reach and the ability to go over obstacles or terrain features. When paired with fire-control systems, this capability translates into fairly precise delivery, reflected in a relatively small CEP for artillery in its class. Mortars, while capable of very high-angle fire, use lower muzzle velocities and have different trade-offs in reach and energy. Cannons typically deliver flatter, higher-velocity fire but with more limited high-angle capability. Rocket launchers can have fast projectiles as well, but their accuracy is often governed by dispersion and guidance, which can yield larger CEP unless highly guided. So, the combination of high muzzle velocity, a broad elevation range, and reliable accuracy points to howitzers.
