In game every single AA uses tracers. However, thats one of the biggest problems with AA: Once you fire at one plane, every other plane is alerted to your position.
How historical is that? Its a hard thing to look up but i’m sure we have some historians here who can answer the question. Were there stealth belts for AA and how common were they?
I feel like non-tracer belt options would really give AA a better fighting chance and the option to use Tracer belts would always be there, much like planes.
