The question here is whether this is a cheat or a bug. Because dataminers have found Damascus files in the game, but this is normal and doesn’t mean that the camouflage will be in the game. For example, in Warzone files, there is even camouflage from Advanced Warfare.
The master camouflages of this game will most likely be: wood, sapphire, jade, onyx. But again, this is in the realm of speculation.
