Although performance in the initial months of the war against Serbia and Russia is often seen as poor, Austro-Hungarian forces were not helped by internal division and indecision among the army high command and possession by Serbian and Russian forces of highly detailed versions of Austro-Hungarian war plans. Overall during the Military's greatest deployment – World War I – and despite persistent fears of disloyalty and division among the Empire's many nationalities, the forces of Austria-Hungary must be seen as having performing largely competently until political demise in late 1918. Imperial forces performed with both great proficiency – the Otranto Raid, Caporetto, and the dogged defence of the Isonzo; and with appalling effect – the Galicia Campaign, the Brusilov Offensive and Vittorio Veneto; as well as at a variety of standards in between. Ultimately, and with much German support, Imperial armed forces held firm, and without much by way of large-scale defections among what were seen as 'suspect' elements of the population until the dying days of the war when political dissent at home led to large-scale defeats both on the front and at Sea as the war came to a close.
