Yes. Actually fairly extensively,particularly in the various colonial wars of the 1945–1960 era. Post WWII France used captured/requisitioned German & to an extent Japanese equipment during it’s colonial war in Indochina (1946–1954), including small arms, aircraft, even clothing. The iconic German MP 40 sub machinegun, the “Schmeiser” & the MG 34 machine gun were employed by the French, then the Viet Cong, & ARVN during both Indochina Wars. The French also made use of the Walther P 38 pistol post war, some of these were made in German factories taken over by the French in 1945 & in todays collectors market command high prices. The French also utilized both the German Ju 52 transport plane as well as the Fieseler “Storch” as a light observation, flare, & general utility aircraft in Indochina.
A plethora of Japanese aircraft were used by the French in the early days of the war in Indochina including fighters, bombers, & in particular maritime patrol aircraft. The Ki 43 “Oscar” fighter, the Ki43 “Sally” bomber, the Aichi E13A1 “Jake”, the A6M2 “Rufe”, just to name a few. During the Indochina War the Viet Minh employed many Japanese small arms (& even some Japanese artillery) against the French. The Japanese Arisaka 7.7 rifle, Nambu MG, & the Japanese “Knee Mortar” grenade launcher were all utilized. The French also used captured bolts of German camouflage cloth from WWII, both Waffen SS as well as Heer patterns to make uniforms for use in Indochina. During the Algerian War between the FLN & France in the 1950s, the French encountered FLN guerillas equipped with Italian Beretta sub machine guns as well as various Italian made rifles, even Italian steel helmets from WWII, as well as Germ weaponry from WW II.
