Two Estonian cavalry regiments participated in the Estonian War of Independence, along with smaller cavalry formations; every infantry regiment had one reconnaissance cavalry attachment. By the end of the war, another cavalry regiment, the Cavalry Reserve Regiment, was formed in Tallinn, and functioned as a cavalry school for soldiers and officers. The Estonian 2nd Cavalry Regiment was dissolved in 1920. Despite several attempts by the Estonian Defence Forces to modernize its cavalry, the units could not keep up with the technological advances of the 1930s and the rapid development of armoured warfare. While already declining before World War II, the remaining Estonian cavalry regiments were abolished and attached to the Soviet 22nd Rifle Corps on 10 September 1940. There have been no cavalry units in the modern Estonian Ground Forces since Estonian independence in 1991. Technical Formations
