1915 Сannon Mountain Skoda 7.5 cm Gebirgskanone M. 15
Its development was quite prolonged, as the Austrians couldn't decide on the specifications that they wanted. Initially, they wanted a gun that could be broken-down into no more than five pack-animal loads to replace the various 7 cm mountain guns in service, but prolonged trials proved that the 7.5 cm M. 12 prototype to be the best gun. However, the commander-in-chief of Bosnia-Hercegovina believe it to be too heavy and demanded a return to the 7 cm caliber to save weight. Skoda dutifully built enough guns for a test battery in the smaller caliber and tested them during the spring of 1914 where they were judged inferior to the 7.5 cm guns. This cost the Austrians heavily as the 7.5 cm guns began to be delivered in April 1915 instead of the planned date of April 1914.
For transport, the gun could be dismantled into six parts, generally carried in four loads. In addition, there was a gun shield fitted on some (perhaps many) such guns. A revised version of this gun was released as the Skoda 75 mm Model 1928.
German anti-tank gunners and supporting infantry, October 1918
The Germans bought some guns during World War I, but used them as infantry guns in direct support of the infantry, as their light weight would allow them to move with the infantry. They complained that the guns were too fragile and didn't have a high enough muzzle velocity to act as an anti-tank gun. Considering that the guns were designed to be disassembled, it's not too surprising that they couldn't stand the abuse moving through the shell-pocketed front lines on the Western Front.
