The show where he went to the FFL in Algeria was all staged. The real FFL training regiment in France, and transferred to other french colonies is a bit more brutal, or was until recently. Since now most Legionaries aren't criminals or run-aways from the lower class, but middle class tourists looking for job opportunities, the FFL is turning into a sort of PMC that is state-run with all the standard military benefits with better pay. It's also getting a "Corporate" reputation, hence the increase in allowed publicity over the years about it's own operations.
