Mountain gun
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 Mountain guns are largely outdated, their role being filled by mortars and wire-guided missiles.
