The Sturmgeschütz III (StuG III) was one of vehicles produced by Germany during WWII. It was based on Panzer III's chassis. Designed as an infantry support tank, it increasingly took on the role of tank destroyer due to its low profile and good cannon. As the most produced tank by Germany during World War II (10,500 units), it thus took on the role of conventional tank warfare. The Sturmgeschütz is also known for its good price to profit ratio. The StuG was manned by four crew members. It was operated by Germany, Italy, Finland, Spain and Syria. These three latter countries retained their StuG IIIs far beyond 1945, being used for example in the Six Day War (1967) by Syria.
