Equipment
By 1934 around 180 anti-aircraft artillerists and 120 anti-aircraft machingunners had received training within the Õhutõrjepataljon. Up till 1938 the unit main task was to maintain the operational equipment. By the summer of 1940 the unit, then called as the Õhukaitse Suurtükiväegrupp had received its technical equipment and menpower peak. The unit inventory included also the 75mm Krupp anti-air guns along with the Carl Zeiss fire guidance systems, 37mm Rheinmetall-Borsig cannons, 40mm Bofors cannons and some additional 76mm Soviet made anti-aircraft cannons. After the Soviet occupation of Estonia in mid 1940 unit was dissolved and the inventory was transferred to the Red Army. The historic weapon inventory up till 1940 included: The Õhutõrjepataljon is currently armed with the 23mm ZU-23-2 anti-aircraft twin autocannons and 90mm Mistral missiles. Since the battalion has no other conventional air defence weapons it is currently capable of providing a limited short-range air defence for the remaining ground units. Both of these weapon systems are integrated with the Giraffe AMB radar and fire-control systems. The current weapon inventory includes roughly: According to the new long-term defence development plan the current air defence battalion will be gradually modernized as one of the priorities of the Estonian Ground Force is the development of capabilities to ensure air defence. According to the plan some mobile medium-range air defence units will be created and developed as along with the existing army short-range air defence capability will be enhanced through the procurement of additional weapons systems and creation of new air defence units.
