What makes a cannon... a cannon?

To add little confusion, Poland rearmed few of their tankettes with 20mm heaviest machine gun

gun
mid-14c., gunne "an engine of war that throws rocks, arrows or other missiles," probably a shortening of woman's name Gunilda, found in M.E. gonnilde "cannon" and in an Anglo-L. reference to a specific gun from a 1330 munitions inventory of Windsor Castle ("...una magna balista de cornu quae Domina Gunilda ..."), from O.N. Gunnhildr, woman's name (from gunnr + hildr, both meaning "war, battle"); the identification of women with powerful weapons is common historically (cf. Big Bertha, Brown Bess, etc.); meaning shifted with technology, from cannons to firearms as they developed 15c. Great guns (cannon, etc.) distinguished from small guns (such as muskets) from c.1400. First applied to pistols and revolvers 1744. Meaning "thief, rascal" is from 1858. The verb meaning "to shoot with a gun" is from 1620s; the sense of "to accelerate an engine" is from 1930. Gun-shy is 1884, originally of sporting dogs. Son of a gun is originally nautical. Gun-metal (commonly an alloy of copper and zinc) used attributively of a dull blue-gray color since 1905.

cannon
c.1400, "tube for projectiles," from O.Fr. canon (14c.), from It. cannone "large tube," augmentive of L. canna "reed, tube" (see cane). Cannon fodder (1891) translates Ger. kanonenfutter (cf. Shakespeare's food for powder in "I Hen. IV"). Spelling not differentiated from canon till c.1800. Cannon ball is from 1660s.
