The Browning M2 heavy machine gun, the ZU-23-2 23 mm anti-aircraft gun, the Mistral and HVM anti-aircraft missile systems and Hellfire missiles fired from AH-64 Apache attack helicopters were used to destroy both flying and sea-based targets. Together with Allies, the Estonian Air Defence Battalion and the Scouts Battalion's anti-aircraft missile unit participated in the live-fire shooting exercise in Rutja. The Estonian Navy supported the shooting exercises by launching waterborne targets from a warship into the target area.
During the first week of Spring Storm which started on May 17, anti-airborne combat techniques and tactics were rehearsed by the Kalev Infantry Battalion, wheres members of the 22nd Infantry Battalion and the 17th Combat Engineer Battalion were responsible for preparing defensive positions. The phase of battle operations, which kicked off on May 24, saw all involved troops fighting against larger bridage-size formations in a wider battle environment. Along with Allies providing close air support, units from the two Estonian brigades played their own adversaries in order to check the level of training of their conscripts and active duty personnel. Conscripts of the 22nd Infantry Battalion had the opportunity to fly in US helicopters to Nurmsi airfield, where they carried out an assault on the positions of the military police's conscripts.
Spring Storm also reached Hiiumaa, the country's second largest island, where the Estonian naval formations practiced coastal defence in cooperation with the Polish Allies, who deployed their naval missile unit with three launchers in support of the exercise.
