Can anyone tell me the rate of fire of the sdkfz/2 mobile anti-aircraft unit?
Can anyone who has tried definitively tell me if the one extra hit point on the /2 model is worth giving up the rate of fire of 140% when upgrading from the 4 barrel 7/1 to the 7/2.
thanks for info

The 4 barrelled German AA guns have 120% RoF.
For me the SPAA are best in a defensive role to deter attacks rather than for shooting up enemy planes. In this role, the combination of -5 low level defence penalty on Fighters and Tac Bombers and higher RoF appears more effective than a slightly better AA value. However, I haven't done a proper stats analysis so can't be completely sure.

sorry yes 120% for the sdkfz/1 (I was confusing it with the panzerflamms 140%).
I always found that 120% quite good and dont normally upgrade to the /2 model but i could making a mistake
