Yes go ahead

Can I upload your Special Forces: PMC's with some edit texture? I got some inspired by ROK SF

I also do wanna make a point that some of my older mods have models from cod4 and battlefield 4

That's awesome, I'd suggest browsing models from gmod/SFM/L4D2, cuz you have authors ripping some pretty obscure but cool looking models from COD. If you see something you like, find that in Cod's source files.

i mainly wanted to ask you some questions regarding the best call of duty models that are very obscure since you seem to rip so many obscure ones

i would like to make a mod for escape from tarkov that i want to source all my assets from call of duty from, but i hate a large sum of the multiplayer models

Depends on the models and I only do commissions :)
