Mountain guns are
artillery pieces designed for use during
mountain combat. They are similar to
infantry support guns, and are generally capable of being broken down into smaller loads (for transport by
horse,
human,
mule,
tractor, and/or
truck). Due to their ability to be broken down into smaller "packages", they are sometimes referred to as
pack guns. Mountain guns are largely outdated, their role being filled by
mortars and
wire-guided missiles.
