The Estonian Land Forces (), unofficially referred to as the Estonian Army, is the name of the unified ground forces among the Estonian Defense Forces where it has an offensive military formation role. The Estonian Land Forces is currently the largest Estonian military branch, with an average size of approximately 6,000 soldiers, conscripts, and officers during peacetime.

The Maavägi development priorities are the capability to participate in missions outside the national territory and perform operations to protect the territory of Estonia, also in co-operation with the Allies. The Maavägi component of the operational structure consists of an infantry brigade and a homeland security structure. Deployable infantry battalion tactical group and some deployable CS, CSS units will develop in the Army structure in accordance with NATO Force Proposals requirements. The infantry brigade will be a training and support frame for deployable units. Homeland security structure units can carry out territorial military tasks and support civil structures.

The Land Forces are structured according to the principle of a reserve force, which means that the main part of the State's defence forces are units in a trained reserve. The reserve units are formed on the territorial principle, i.e. conscripts from one area are called up at one time to one unit and after service, they are sent to the reserve as one unit.

History The 1st and 2nd Divisions were created during the Estonian War of Independence; the 1st Division in December 1918 and the 2nd Division in January 1919. The Scouts Single Infantry Battalion was formed on 21 December 1918.

Eight 'Single Infantry Battalions' were formed on 21 November 1928. The battalions were created to train conscripts during peacetime. In wartime, the battalion would reorganize itself into a regiment with a similar order of battle as the two initial reaction force regiments covering the eastern and southern borders. Each battalion's peacetime strength was a total of 237 soldiers in a regimental staff, a Signal Platoon, an Engineering Platoon, a Ski-Bicycle Platoon, a Building Platoon, and three infantry companies.

The wartime order of battle would have transformed the battalion into a regiment-sized unit with the same unit number. It would have included 3 infantry battalions, Signal Company, Engineering Company, Ski-Bicycle Company, Cavalry Company, Building Company, Commandant Commando, and a CB Commando; all in total of 3,153 men.

The 2nd Single Infantry Battalion was located at Tartu, the 3rd Single Infantry Battalion was located at Valga, the 4th at Jõhvi, the 5th at Rakvere, the 6th Single Infantry Battalion was located at Pärnu, the 8th Single Infantry Battalion at Valga, the 9th at Pärnu, and the 10th Single Infantry Battalion was located at Tallinn.

A reorganisation took place on 1 February 1940 and a fourth division was created. The 4th Division staff was based in Viljandi. The division was made up by the Pärnu-Viljandi Military District and Valga Military District. The division's commander was Colonel Jaan Maide. The four divisions were active until the Soviet occupation of Estonia.

On 17 August 1940, after Estonia was occupied by the Soviets, the 22nd Territorial Rifle Corps of the Red Army was formed at Tallinn. The Army was created as a territorial Estonian body based on military units and institutions of the Estonian army. All soldiers and officers kept the Estonian Army 1936-spec uniforms but with Soviet insignia. The first commander of the 22nd Territorial Rifle Corps was a former major general of the Estonian army, Gustav Jonson, who was later arrested by the NKVD and shot. Most of the corps' officer posts were occupied by former officers of the Estonian Army. By the middle of June 1941, before the German invasion of the Soviet Union; most of the Estonian Army officers were arrested and replaced by newcomers from the Soviet Red Army officers.

Many of the Estonian officers of the 22nd Territorial Rifle Corps body were arrested and died in 1941 and 1942 in camps in the Soviet Union; many were shot. The former commander of the 180th Rifle Division, 22nd Corps, Richard Tomberg, survived after dismissal only because from 1942 He was claimed by the Frunze Military Academy as a teacher. He was arrested in February 1944 (He was later released from the camp and rehabilitated in 1956). Some officers of the 22nd Rifle Corps, among them Alfons Rebane, managed to escape from the authorities in the period between dismissal from the army and the plan for their arrest. Some managed to escape abroad, others came out of hiding only after the arrival of German troops in July and August 1941, some of them volunteered for the Estonian units that fought on the side of Nazi Germany or enlisted in Estonian organisations controlled by the Germans.

The 22nd Territorial Rifle Corps was part of the 'operational army' during World War II from 22 June 1941 to 31 August 1941. On 22 June 1941, the 22nd Territorial Rifle Corps headquarters was stationed in the village of Rev.
