The armed forces of many nations have, at one time or another, used foreign volunteers who are motivated by political, ideological or other considerations to join a foreign army. These may be formed into units of a given nationality or may be formed into mixed nationality foreign units. Sometimes foreign volunteers were or are incorporated into ordinary units. The practice has a long history, dating back at least as far as the Roman Empire, which recruited non-citizens into Auxiliary units on the promise of them receiving Roman citizenship for themselves and their descendents at the end of their service

Reasons for volunteering
Three main reasons for volunteering can be identified:
- Ideology - the volunteer believes in a cause and volunteers to fight for it.
- Adventure - the volunteer joins a foreign army to see action.
- Long-term personal or family benefit - the volunteer serves in order to qualify for non-financial benefits, such as forgiveness of sins, citizenship or to acquire an education.
This is a simplistic analysis and, in many cases, a volunteer will be influenced by two or more of these reasons. It follows, therefore, that a unit of foreign volunteers may contain soldiers with different, or different combinations of, motivations.
Mixed nationality units
- 62nd (Royal American) Regiment of Foot. Composed of 'foreign Protestants'.
- French Foreign Legion
- Hohenlohe Regiment of France during the Bourbon Restoration.
- International Brigades of the Spanish Civil War
- Islamic Legion

- Mahal - non-Israeli volunteers who fought for Israel in the 1948 Arab-Israeli War. There is to this day a Mahal program in the Israeli army.
- The SS (particularly the Waffen-SS) made extensive use of foreigners during World War II. For more information, see: Europäische Freiwillige, Foreign volunteers and conscripts in the Waffen-SS.
- Tercio de Extranjeros, or Tercio, or Spanish Legion - prior to 1987 and in the 2000s, after the abandonment of conscription, the Spanish Army is again accepting foreigners from select nationalities. The Legion today accepts male and female native Spanish speakers, mostly from Central American and South American states. Recruits are required to have a valid Spanish residence permit.
- Rhodesian Light Infantry (initially all-Rhodesian, this unit became the "Foreign Legion" of the Rhodesian Army)
- The United States Military has a long tradition of foreign volunteers taking up arms for the United States. Foreign born officers, such as the Marquis de Lafayette, Tadeusz Kościuszko, and Friedrich Wilhelm von Steuben provided vital contributions to the cause of independence. During the nineteenth century the US Army made extensive use of foreign soldiers, particularly Irish and German. German Jewish troops were common during World War II. Presently, many members of the US Marine Corps are of Latin American and not US nationality. However, many if not most non-American troops in the United States armed forces are usually seeking the expedited United States citizenship that comes with completion of a term of service, and can be seen as aspiring Americans rather than outright foreigners.
