why nobody got Cobras Distinguished Service Medal yet?

Medals have not been given out yet.

are the medals still in production?

? Medals haven't been given out yet, but they will be soon.

i thought they were still being made, like the models, the textures and stuff

Medals are already uploaded to the store and you can find them by turning off the "Hide Off-sale" filter in the store. They have not been given out yet and I don't know when they will.

Medals have since been given out.
