speed=The 8 cm Feldkanone M. 99 was a field gun used by Austria-Hungary in World War I. It was designed in a rush because Austria-Hungary's neighbors had already begun the process of modernizing their artillery. This forced the Austrians to make whatever improvements that could be made without delaying the development process. For example various hydraulic recoil systems were evaluated, but ultimately rejected as they required more development time than was available. So the M. 99 retained the bronze barrel of its predecessor, but used a eccentric interrupted-screw breech to speed up its rate of fire, and adopted the carriage of the 9 cm Feldkanone M 75/96 with some minor changes, including improvements to the spade brake to reduce recoil forces.
