Twin and quad MGs and Autocannon ROF

Can you help me?
What is the ROF of:
- twin MGs
- quad MGs
- twin 20mm autocannons
- Typhoon's 4 20mm autocannons
- SdKfz 251/21 3 x 15mm 'Drilling'

Thanks

All dual and quad mounted small arms and auto cannot are maximum RoF of 10.

They also roll twice for suppression.

You can look at them pretty much as 2 separate weapons systems firing at the same time, at the same Target.

They are absolutely devastating to infanty. I use an M-16 spaa alot to just pin forward observers and mg teams and to eat any infantry that get close. Once you use them you can see why they are restricted.
