WWII US Army Flaming Bomb T Shirt

The Shell and Flame (a.k.a. Flaming Bomb) has been used by European armies for several centuries before adoption by the U.S. Army. In fact, it is still used by many countries in Western Europe, i.e. the Grenadier Guards in Britain. The insignia represents not a bomb, but an iron hand grenade with a powder charge and a fuse which had to be lit before throwing.
