Maybe Shemp can help on this.

I cracked open a new DVD I purchased some months ago out of the dollar bin.  I peeled it open for the first time this weekend.  It has Stan and Ollie in the French Foreign Legion for most of the movie, Flying Deuces. 

At the outset of the movie, though, the duo are civilians visiting Paris.  As it happens they are a scant few hours from having to catch their ship back to the states.  Situations cause them to stay in Paris and eventually join the Foreign Legion.  I won't go into details so as to not spoil the plot.

During the course of the film the boys go back and forth from wearing civilian tourist clothes to Legionnaires in uniform.  During their times in civilian dress they each have a ribbon on their left lapel.  These are wide flat ribbons such that you would find at a county fair, approx 2"wide and 8" - 10" long.  These single ribbons are topped with a roundel with a logo on it.  It is the letter 'C' superimposed on a letter 'T', or vicey-versy.

Does anyone know what these ribbons signify and why the letters 'T' and 'C'?
