Several European countries also acquired the rifle, all in the 7.92 mm caliber. The Lithuanian Army acquired the vz. 24 in the 1930s, and many of these rifles were captured by German forces during Operation Barbarossa before falling into the hands of the Soviet Army later in the war. Some of these rifles were then sent to Vietnam to arm the Viet Cong, and some were captured a third time by American forces during the Vietnam War. Yugoslavia purchased 40,000 rifles in 1926, all of which came from Czechoslovak Army stockpiles, and a further 10,000+ between 1928 and 1930. These rifles saw action during World War II during the German invasion of Yugoslavia in April 1941, as well as during the Partisans' insurgency against the German occupation. In 1935, Latvia traded surplus No. 1 Mk. III Lee–Enfield rifles for 15,000 vz. 24s; Brno Arms Works in turn sold the Lee–Enfields to Iraq. During World War II, Latvian resistance fighters employed the vz. 24s that had been ordered by the Latvian Army against the German occupation forces.
