Hello there,
I always loved the look of the Spec-Ops uniform and all around it, but we as a community usually just fight with the Liberator Gear.
Despite it's low cost (you can trade it with an Ensign) it offers different clothing for different ranks which is a big plus for a group that uses military ranks.
I don't think that the Ghillie gives you that much of a "invisible" effect in the woods, or maybe I'm just a hawkeye since I never got fooled by a Ghillie in this game.
You can see players run in the distance without any plants or trees rendering, so I don't see the point of having an expensive Ghillie.
See you,
