Perhaps some gun abbreviations could implement what guns are hit, or using number stations for the guns like:
"Gun" labels on the Corsairs would instead be "LO Gun, LC Gun, LI Gun", or "Gun 1, Gun 2, Gun 3".
Same thing with the Tempest/Typhoon cannons: "LO Cannon, LI Cannon", or "Cannon 1, Cannon 2"
Say that you're flyin a Spit1, you're dogfighting, and your guns get taken out in flight. You would kike to know exactly which gun(s) were hit, but when you hit the ctrl+D key, all you see is "Gun Damaged". You don't know which gun was hit, so already you're a bit flustered. Of course, you could check in many ways(I fire a quick burst to check while looking at the wings imo).
Whereas you dogfight, get guns hit, open ctrl+d and see "Gun 1 Damaged" or "FOL(Far Outer Left)Gun" in red, you know exactly that your far outer gun is gone.
