Here is a clip that just popped up in my YouTube feed. It is an English language video about the Foreign Legion produced by France 24 that appeared there on 27 April. It is really well done thematically and filmed in beautiful high quality video. The reporter follows a section of the 13th DBLE (now located in France) during their deployment to southern Mali as part of Operation Barkhane. There is no combat during the six days the reporter spent embedded with the Legion but what comes across in the individual interviews and background is extremely enlightening. This is very well worth the time to watch.
UPDATE: Here is a more recent supplement to the above video. Shorter but provides more insight and commentary of the same Legionnaires–mainly about their motivations for joining.
