The Estonian Defence Forces (Estonian: Eesti Kaitsevägi) is the name of the unified armed forces of the Republic of Estonia. The Estonian military is a defence force consisting of Estonian Land Forces, Merevägi (Navy), Õhuvägi (Air Force) and a paramilitary organization Kaitseliit (Defence League). The national defence policy aims to guarantee the preservation of the independence and sovereignty of the state, the integrity of its land area, territorial waters and airspace and its constitutional order. Its main goals remain the development and maintenance of a credible capability to defend the nation's vital interests and development of the Defence Forces in a way that ensures their interoperability with the armed forces of NATO and European Union member states and their capability to participate in the full range of Alliance missions.

After the German Revolution, between 11 and 14 November 1918, ending the German occupation in Estonia, the representatives of Germany formally handed over political power to the Government of Estonia. A few days later Estonia was invaded by the military forces of Bolshevist Russia, marking the beginning of the Estonian War of Independence. The small, poorly armed Estonian military, also known as the (Estonian: Rahvavägi) (Peoples Force), was initially pushed back by the Red Army into the vicinity of the capital city of Estonia - Tallinn. A mere 34 kilometers separated Tallinn and the front line. Partly due to the timely arrival of a shipment of arms brought by a British naval squadron the Bolsheviks were stopped.

Johan Laidoner (12 February 1884 in Viiratsi, Estonia – 13 March 1953 in Vladimir, Russia) was a seminal figure of Estonian history between the world wars. His highest position was Commander-in-chief of the Estonian Army in 1918–1920, 1924–1925, and 1934–1940.

Laidoner was born in Raja farmstead near Viiratsi (site now located in Vardja village, Viiratsi Parish), Viljandi County, Governorate of Livonia, then part of the Russian Empire. As a boy he worked as a herder during summers and attended parish school during the rest of year. In 1901, he volunteered for the army. He was first stationed in Kowno, Lithuania as a member of an infantry regiment. In 1902 he entered the military academy in Wilna, where he also met his future Polish wife, Maria. Laidoner continued his military education in 1909 at the Nikolai Military Academy in St. Petersburg.

Following his graduation from the Imperial Nicholas Military Academy, Laidoner achieved the rank of lieutenant colonel in the Russian Army. He received seven medals before the Russian Empire dissolved.

John Sidney McCain III (born August 29, 1936) is the senior United States Senator from Arizona. He was the Republican presidential nominee in the 2008 United States election.

McCain followed his father and grandfather, both four-star admirals, into the United States Navy, graduating from the U.S. Naval Academy in 1958. He became a naval aviator, flying ground-attack aircraft from aircraft carriers. During the Vietnam War, he was almost killed in the 1967 USS Forrestal fire. In October 1967, while on a bombing mission over Hanoi, he was shot down, seriously injured, and captured by the North Vietnamese. He was a prisoner of war until 1973. McCain experienced episodes of torture, and refused an out-of-sequence early repatriation offer. His war wounds left him with lifelong physical limitations.

He retired from the Navy as a captain in 1981 and moved to Arizona, where he entered politics. Elected to the U.S. House of Representatives in 1982, he served two terms, and was then elected to the U.S. Senate in 1986, winning re-election easily four times, most recently in 2010. While generally adhering to conservative principles, McCain at times has had a media reputation as a "maverick" for his willingness to disagree with his party on certain issues. After being investigated and largely exonerated in a political influence scandal of the 1980s as a member of the Keating Five, he made campaign finance reform one of his signature concerns, which eventually led to the passage of the McCain-Feingold Act in 2002. He is also known for his work towards restoring diplomatic relations with Vietnam in the 1990s, and for his belief that the war in Iraq should be fought to a successful conclusion. McCain has chaired the Senate Commerce Committee, opposed spending that he considered to be pork barrel, and played a key role in alleviating a crisis over judicial nominations.
