Who sells RPG rocket ammo?

Is there any trader that actually sells them?

As far as im aware they're only found in very limited quantities out in the open world(like 25 total in the whole game or so)

This has been a problem in all 4 stalker games where RPG rockets were not sold anywhere (except Call of Pripyat but u had to take a faction side and ruin rep with another faction for them to appear in traders inv) and otherwise in other 2 games u relied on a weird engine trick to generate rockets from pistol only npcs lol.

Developers seem to have a hate for RPG rocket ammo
