Grenadier was the lowest rank in the Heer, the army of the Third Reich. It was also known as Schütze. Although I have been unable to determine how many soldiers in the Heer had this rank, it can be expected that it was at least half of them, meaning roughly 1 800 000 in 1939 and as many as 3 250 000 at a time in 1943. As a comparison, 24 620 748 German men were aged 15-65 in 1939.

The Luftwaffe equivalent to Grenadier was Flieger, the Kriegsmarine equivalent was Matrose and the Waffen-SS equivalent was SS-Schütze. The equivalent US Army rank is Private.
