A few tips on useing Ghille.
- snipers devote a large part of their training to using this piece of equipment, just owning one does allow you to take advantage of it.
- Ghille suits are very flammable, make sure that you buy a fire retardant spray, and use it on the suit.
- I found that in paintball ( which I will admit is not at all the same game) setting yourself up for an ambush with ghille actually takes you out of the action. You are at the mercy of fate because you have to wait for players to stumble into your ambush spot. Moving will negate any advantage you gain from a ghille.
I would suggest playing for a while before investing/creating a ghille suit to determine your playing style, you may find you don't enjoy sniping and regret having purchased a suit.
