The Volunteer combatant's cross 1914–1918 is a French decoration that recognizes those who volunteered to serve on the front in a combat unit during World War I. When the 1914–1918 Commemorative war medal was established, it was anticipated that a clasp bearing the words, "ENGAGÉ VOLONTAIRE", would be worn on its ribbon for those who had freely and voluntarily enlisted in the French Armed Forces for combat service.
