Slightly off-topic, but I highly suggest Jean Larteguy's highly accurate novels of life in the French Foreign Legion in the post WWII period. The Centurions and The Praetorians are a good place to start.
There was a book called the devil's guard or the devil's brigade or something like that about some german ss troops that witnessed a massacre of regulararmy troops by the russians, they went across europe & joined the foriegn legion & fought in french indochina until uncle ho had their story published in paris newspapers & they were discharged & retired to nepal (i think - its been 20-25 years since i've read it)
Take it with a grain of salt i've been told it was true & that it was bs both by different army intel officers that served in the 50's- 60's but it was a good read
