Customizable belting pattern and visually modeled bullets?

[Pursuivant]

I don't think it's possible to model individual bullets in IL-2.

For that reason, it might be impossible for players to choose customized ammo loadouts.

OTOH, it doesn't seem like it would be that much trouble to add different "stock" MG loadouts for different missions.

Another MG option, which could be a GUI option rather than a loadout option, would be the option to change the color of tracers or have different colored tracers at the end of the MG's load (used by some units).

Something that could be an option, but is technically a loadout, would be to change the frequency of tracer rounds. Some units didn't use tracers at all, some used more than the standard number as substitutes for incendiaries.
