I want to know the answer to the following question:
A secretive army installation began in Kummersdorf-West in what year?
All the background I'm provided with is that "The head of the German Army's Ballistics and Munitions Branch, Lieutenant Colonel Karl Emil Becker, gathered a small team of engineers that included Walter Dornberger and Leo Zanssen, to figure out how to use rockets as long-range artillery in order to get around the Treaty of Versailles' ban on research and development of long-range cannons.". Is that enough to answer the question?
Answer: no
