My group/clan, SE.VH, hasn't attacked those targets because whenever we've tried, most of them have died or been severely damaged. We prioritize survival, and we're not a very large group/clan. I don't know the minimum number needed to attack those targets and have most of them survive, even if damaged. I've been wanting to know this lately because sometimes I see three attacking defense or attack targets, and I wonder if it's because they're using the IL-2 or if the A-A isn't powerful enough at a certain altitude. (I know it's good that these defense and attack targets are difficult because they're very important for the teams' advance or defense.) (Note: If my English is bad, I apologize; I'm not very good at English. I just wanted to know what list of aircraft is currently available in the front line and in what years they are released. I have this question.)
