The Support Command of the past played a critical role in winning the War of Independence, as this structural unit had to provide the National Army with everything they needed for combat – arms, ammunition, supplies, clothes, shelter, and food. This means that the Estonian military logistics and the support command have the right and honour to call themselves one of the winners of the War of Independence and, consequently, founders of the Republic of Estonia.
Today, in many NATO countries, military logistics are regarded as the so-called fourth armed service beside the land, sea and air forces. As the so-called fourth armed service of the Estonian Defence Forces, the Support Command must ensure the daily functioning of the Estonian Defence Forces.
The Support Command ensures that the Estonian Defence Force units have ammunition, arms, equipment and means of transport. The Support Command also provides medical services to the Estonian Defence Forces. The Support Command supports all units of the Estonian Defence Forces participating in military operations with the necessary ammunition, arms, equipment and means of transport.
