A lot of East Africans have grandpas who fought in Burma during ww2 [1]. In fact a certain suburb in Nairobi is called Kariokor; a bastardisation of the name carrier corps.

(possibly inaccurate, but a tremendous story - the man who fought, against his will, for three different sides of WW2)

https://en.wikipedia.org/wiki/Yang_Kyoungjong

"In 1938, at the age of 18, he was in Manchuria when he was conscripted into the Kwantung Army of the Imperial Japanese Army to fight against the Soviet Union.[1] At the time, Korea was ruled by Japan.

During the Battle of Khalkhin Gol, he was captured by the Soviet Red Army and sent to a Gulag labor camp.[3]

Because of Soviet manpower shortages in the fight against Nazi Germany, he was pressed, in 1942, into fighting in the Red Army, along with thousands of other prisoners. He was sent to the Eastern Front of Europe.[3]

In 1943, he was captured by Wehrmacht soldiers in eastern Ukraine during the Third Battle of Kharkov, and then joined the "Eastern Battalions" to fight for Germany.[3] Yang was sent to Occupied France to serve in a battalion of former Soviet prisoners of war on the Cotentin peninsula in Normandy, close to Utah Beach.[citation needed] After the D-Day landings in northern France by the Allied forces, Yang was captured by paratroopers of the United States Army in June 1944.[citation needed]

The Americans initially believed him to be a Japanese soldier in German uniform; at the time, Lieutenant Robert Brewer of the 506th Parachute Infantry Regiment, 101st Airborne Division, reported that his regiment had captured four Asians in German uniform after the Utah Beach landings, and that initially no one was able to communicate with them.[citation needed] Yang was sent to a prison camp in Britain and later transferred to a camp in the United States.[citation needed]"
