The British say a lot of things, some true, others, not so much.
I've read British reviewers works on lots of things, and the one thing they all seem to have in common is that if its not British, its flawed in some way.
WWII US fighter planes were described as having cockpits like "executive offices" (large) and complain about all the "wasted space". And, our flight instruments are all in the "wrong" places....
they examined a captured Tiger tank, and concluded how difficult it would be to operate, due to the cramped crew spaces.
German crewman felt otherwise, one driver said how he loved the amount of space in the Tiger, there was actually enough room for him to sleep in the tank, something none of the earlier tanks had...
Its all point of view, I guess....
If a quad .50 isn't firing all 4 guns (and is set to fire all 4 guns) then something is broken and needs fixing.
