Two years after the end of Lithuanian Wars of Independence (1918–1920), the Lithuanian Army consisted of 4 infantry, 1 cavalry divisions, 4 artillery regiments and a number of small independent battalions and companies.
In 1921, the year's military budget was 491 million auksiniai which was 54.75% of all states outcomes. One year later, in 1922, state outcomes for defence were 4312 million auksiniai (42.66% of the state budget).
Infantry dislocation was impacted by changes of Lithuanian borders. Infantry regiment was the primary forces defending the country. Lithuania was surrounded by enemies. Only Latvian side was safe. Other borders required cover.
