@joelmar can you give an example of the 20 mm? My general impression so far has been that most combat casualties are from retreating and even high efficiency destructive weapons don’t really change the CV ratios that much.
Honestly, I hadn't tested the 20mm quads myself, it's Crackaces who did and is always very adamant about that. But I just tested running 3 times the same battle at mess level 7, I attacked a stack of cavalry corps with divisions loaded with 20mm quads directly attached, and couldn't reproduce what he found, in 3 battles the quads didn't even fire one shot that I could see. But Crackaces says he has witnessed their effects many times, so I have to take his word on it.
No, SU's don't change the final ratio that much, that's not their job. They contribute to the harrassment of the enemy. But that small contribution is often the little boost that makes the difference, same for air power.
When there is a retreat, any damaged element has much more chance of being captured, so the damage that can be done during combat augments the final combat casualties after the final calculation of CV.
I find 88's to have the most impact on air. I started off attaching SP Flak but they werent as effective as the 88's for kills. I only use SP Flak when no mixed or heavy flak arent available to attach.
Yes, that's my tendency too. But SP flak has the advantage of being motorized, so they don't require more trucks from the pool to get motorized when attached to motorized divisions and add a little CV to the division, which is a great part of their value.
But from my experience, when attaching SP flak directly to divisions, they don't contribute flak, only CV for ground attack.
