realistic AAA numbre of guns for 70s.

[Baco]

Hi I was wondering, how much AAA is realistic, I know its cheap, its common but how many guns, 4, 6 12 24 per target?

Zu 23 and specially zsu 23 are very accurate.

 

And when flying 2000 aircraft is barely noticeable,  but flying the Scooter and early 70s aircraft is very, very deadly specially if combined with SA2 and 3 systems...
