Correct. Before the introduction of the MAT 49, the standard issue, PM MAS 38, had become obsolete and many airborne battalions were equipped with MP40s, taken from the German stocks left in France after the end of WW2.
MP40, I'm sure the use of German equipment was extremely prevalent, massive stockpiles to rearm certain units until a standard can be reached. The French military was a soup of equipment up until the late 50's
As you’ve mentioned Roger Faulques, he gave to the salle d’honneur the battle dress jacket he was wearing during the operation of the evacuation of Cao Bang along the RC4, in September-October 1950. The operation turned into a disaster where 1er BEP was annihilated. Faulques was severely wounded and captured by the Viets. Convinced that he wouldn’t survive they allowed his medevac back to Hanoi.
One could still see the holes in the jacket caused by the bullets/schrapnel that hit him.
Below the uniform (US origin) worn by paras units in 1950 in Indochina.
During and after the end of World War II, many MP 40s were captured or surrendered (upwards of 200,000) to the Allies and were then redistributed to the paramilitary and irregular forces of some developing countries. The Norwegian army withdrew the MP 38 from use in 1975 but used the MP 40 for some years more. In particular, the Territorials (Heimevernet) used it until about 1990, when it was replaced by the Heckler & Koch MP5."
2REP museum...photos from my time working on the extension "late 1993. I enjoyed it immensely. The legendary Roger Faulques and other 1REP veterans payed us a visit to ask about the work when they were in Calvi. By the way, the Régimental colours/drapeu is kept in the museum. The photo of the table is where you present yourself to the Chef de Corps on the morning of guard 24.
