Claim:
A carriage for a field gun, the field gun being convertible between a travelling condition and a firing condition, the carriage comprising: a first component for occupying a first travelling configuration when the gun is in the travelling condition, and for occupying a first firing configuration when the gun is in the firing condition; a second component for occupying a second travelling configuration when the gun is in the travelling condition, and for occupying a second firing configuration when the gun is in the firing condition, the second component comprising an extensible front leg having a wheel for contacting the ground plane at a front ground contact point in both the second travelling configuration and the second firing configuration; and a link connecting the first and second component, wherein a manipulation of the first component from the first travelling configuration to the first firing configuration actuates a relocation of the second component between the second travelling configuration and the second firing configuration while maintaining contact between the wheel and the ground plane.
