peacetime, in addition to their traditional guerilla activities in times of war. Three anti-aircraft regiments were formed in the same year. 1933–1937 In early 1933, there was a war scare regarding Italy and Hungary which greatly concerned the General Staff. The British military attaché observed that the army had great self-belief, its infantry was tough and its artillery was well-equipped, but it greatly lacked in significant areas required by a modern fighting force. Key deficiencies remained in machine guns and infantry guns, and there was no combined arms training. The attaché further observed that, along with the almost complete Serb domination of the general ranks, the General Staff was also 90 per cent Serb, and "Serbianisation" of the army had continued, with young educated Croats and Slovenes now reluctant to enter the army. The attaché saw the Serb domination of the army as a possible political weakness for the nation, but also a military weakness in time of war. Three Croat officers were promoted to the rank of brigadni đeneral during the year. There were also reductions in the numbers of artillery regiments and batteries, and infantry battalions and companies, due to significantly lower conscription numbers for 1933, which were caused by the Balkan Wars twenty years earlier. Three more anti-aircraft regiments were formed, and an independent command was created for Šibenik in Dalmatia. Long-term shortages in officers and non-commissioned officers (NCOs) remained, with deficiencies of 3,500 officers and 7,300 NCOs. Disturbances in the Macedonian region resulted in the issue of 25,000 rifles to members of the Serb-nationalist paramilitary force Narodna Odbrana. In June 1934, Army general Milan Nedić became Chief of the General Staff, replacing Milovanović. King Alexander appointed Nedić to carry through a significant change in army organisation against the opposition of many of the senior generals, mainly to reduce the size of the oversized infantry divisions and create corps as an intermediate formation between divisions and armies. After Alexander's assassination, Nedić decided to defer the changes, citing practical difficulties. A chemical warfare battalion was also formed, with the intention of providing each army with one company. Trials were also undertaken with Skoda tankettes and a locally designed automatic rifle. It was announced that army-level manoeuvres would be held in 1935, for the first time since the formation of the army in 1919. A commission formed to examine the issue of mechanisation of the army concluded that the
