it does for LT and MBTs but i dont think it does so much for SPAA/Gs
Unfortunately its only indirect.
Max elevation speed should likely be 42.2 degrees/sec or 750 mils/sec. But the gunner would only be able to manually input 25 degrees pr second. Same as an Abrams. I get these numbers from the AFAADS (Advanced Forward Area Air Defense System) concept that birthed GLAADS and later ARGADS then DIVAD. The requirement was to be able to engage planes passing by at 200m distance at 300m/s:
This is why the Sgt York can rotate 90 degrees/sec. Another way to look at it is that basically the system had to be able to point to point its guns in the complete opposite direction within 2 seconds to fulfill the requirement of starting the engagement within 6 seconds from threat detection.
But the only video we have of the M247 with significant length moving its guns shows the slower manual elevation speed. Which is my guess as to why Gaijin gave it 30 degrees/sec.
Unfortunately, it’s not a direct source so we can only pray that the snail gods discover this truth themselves.
