20th and 21st Centuries
Cannon in the 20th and 21st centuries are usually divided into sub-categories, and given separate names. Some of the most widely used types of modern cannon are howitzers, mortars, guns, and autocannon, although a few superguns—extremely large, custom-designed cannon—have also been constructed. Modern artillery is used in a variety of roles, depending on its type. According to NATO, the general role of artillery is to provide fire support, which is defined as "the application of fire, coordinated with the maneuver of forces to destroy, neutralize, or suppress the enemy."
When referring to cannon, the term gun is often used incorrectly. In military usage, a gun is a cannon with a high muzzle velocity and comparatively flat trajectory, as opposed to other types of artillery, such as howitzers or mortars, which have lower muzzle velocities, and usually fire indirectly.

Famous quotes containing the word centuries:
“The Cad is the entire epitome, the complete blossom and fruit in one, of what we are told is an age of culture. Behold him in the vélodrome as he yells insanely after his kind as they tear along on their tandem machines in a match, and then ask yourself candidly, O my reader, if any age before this in all the centuries of earth ever produced any creature so utterly low and loathsome, so physically, mentally, individually, and collectively hideous?”
—Ouida [Marie Louise De La Ramée] (1839–1908)
