French Foreign Legion 4th Repair Company pocket badge

The 4th Repair company was created on the 16th August 1949 and was based in Langson on the Route Colonial 4, the company spends the next year on operations on the RC4 usually working with the 3e REI. Their job is the recovery and repair of the damaged vehicles (an enormous task given how often the Viet ambushed the troops on the RC4 and Sabotaged the RC4).
