I want to know the answer to the following question:
How many of the M2HB guns were mounted together on the M45 Quadmount weapons system?
All the background I'm provided with is that "Their needs could cogently be met with smaller-calibre ordnance beyond using the usual singly-mounted M2 .50 caliber machine gun atop a tank's turret, as four of the ground-used "heavy barrel" (M2HB) guns were mounted together on the American Maxson firm's M45 Quadmount weapons system (as a direct answer to the Flakvierling),which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft.". Is that enough to answer the question?
Answer: yes
