I want to know the answer to the following question:
What was placed on the blockhouses by the Germans?
All the background I'm provided with is that "The Germans developed massive reinforced concrete blockhouses, some more than six stories high, which were known as Hochbunker "High Bunkers" or "Flaktürme" flak towers, on which they placed anti-aircraft artillery.". Is that enough to answer the question?
Answer: yes
