The Brazilian Expeditionary Force (in portuguese: Força Expedicionaria Brasileira)
This has to be my favourite military insignia of WW2. It’s so unwarlike it looks more like Hissing Sid.Brazil declared war on Germany in 1942 and the 27,000 strong BEF fought with the Allies in Italy from 1944. The smoking snake emblem was adopted because it had been said in Brazil that a snake was more likely to smoke than Brazil enter the war! The BEF was the only racially unsegregated unit to fight in Europe.
