The 27 BCA was created at 1871 Rochefort on January 30, 1871. From 1889 it was designated as an alpine unit (
chasseurs alpins). During the Second World War, it notably took part in the
Battles of Narvik. After it was disbanded after
Case Anton, some of its elements trained the
Maquis des Glières; in subsequent combat against SS units the Battalion gained the motto of
Vivre libre ou mourir ("live free, or die"). Some 129 men of the unit died in the war. It took part in the
Algerian War, in Kabily, until 1962. From November 2008 to June 2009 the 27 BCA has been engaged in
Afghanistan, notably taking part in the
Battle of Alasay. The unit returned to Afghanistan in November 2011, serving in the Kapisa valley and receiving a second citation at the army level and a rare second fourragère. In February 2022 the unit was deployed to Romania. ==Commander==
