From the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon.By this time, the trunnion (a short axle protruding from either side of the gun barrel) had been developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iron band, the "capsquare".

Horse artillery—rows of limbers and caissons, each pulled by teams of six horses with three postilion riders and an escort on horseback (1933, Poland). A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed.
The seven-barrel carriage assembly itself is driven by the aircraft's dual hydraulic system. [14] The GAU-8/A ammunition feed is linkless, reducing weight and avoiding a great deal of potential for jamming. The feed system is double-ended, allowing the spent casings to be returned to the ammunition drum. [15]
The Canon d'Infantrie de 37 modele 1916 TRP (37mm mle.1916) was a French infantry support gun, first used during World War I. The gun was used by a number of forces during and after the war.

The 3-inch ordnance rifle was mounted on the standard carriage for the 6-pounder field gun. Because its projectile was heavier than a 6-pound shot, the 3-inch rifle's greater recoil sometimes caused damage to the trail or the cheek pieces of the carriage.
