 Inter-division manoeuvres were again undertaken in three regions, but cavalry charges and massed infantry attacks demonstrated that the army had not learned the lessons of World War I.In the view of the British military attaché, the clique of Serbian officers in charge of the army at this time were narrow-minded and conservative men who, while keen to modernise the equipment of the army, did not see the need to modernise its tactics or organisation, and were unwilling to learn from others.During following year, a machine gun company was created in each infantry battalion, and both the "Savska" (Zagreb) and "Dravska" (Ljubljana) divisions converted one of their infantry regiments into a mountain infantry regiment.
