A tirailleur (French: [tiʁajœʁ]), in the Napoleonic era, was a type of light infantry trained to skirmish ahead of the main columns. Later, the term "tirailleur" was used by the French Army as a designation for indigenous infantry recruited in the French colonial territories during the 19th and 20th centuries, or for metropolitan units serving in a light infantry role.
The French army currently maintains one tirailleur regiment, the 1st Tirailleur Regiment. This regiment was known as the 170th Infantry Regiment between 1964 and 1994. Prior to 1964, it was known as the 7th Algerian Tirailleur Regiment, but changed its name after it moved to France as a result of Algerian independence.
