Abstract

An adjustable, easily erectable field piece settable at variable elevation angles is described. A two-point support is adapted to pivotally carry an intermediate member which is affixed to a composite sleeve serving as a barrel support member. A mortar breech mechanism is affixed to a first telescopic leg of the two-point support, and is pivotally mounted in a ground plate at such first base point to removably engage the rear end of the barrel when the barrel is at an upper elevation angle suitable for mortar application. A separate cannon breech mechanism is pivotally carried by the rear end of the barrel for selective firing engagement with the rear end of the barrel when such barrel is moved by the two-point support to a relatively low elevation angle suitable for cannon applications.
