speed=The 7 cm Gebirgsgeschütz M 99 was a mountain gun used by Austria-Hungary during World War I. It was obsolete upon introduction as it had a bronze barrel and only a spring-loaded spade to absorb the recoil forces and it had to be relaid after every shot. Although, to be fair to the Austro-Hungarians, the high elevations required of mountain guns greatly complicated the provision of barrel recoil systems as the breech could recoil right into the ground, and it would be some years before satisfactory systems were worked out. These would result in the 7 cm Gebirgsgeschütz M 8 and M 9 that used the same barrel and ammunition as the M 99, but had gun shields and proper recoil systems. These guns weighed convert|402|kg|lb and convert|456|kg|lb respectively, although the exact differences between them are unclear other than they broke down into four and five loads for transport respectively.

The Gebirgsgeschütz M 99 broke down into 3 loads for transport.
