just like territories, but you start with a sniper and assault rifle. and when you get near a flag, you go camo (whether you're on offense or defense). it makes it a little harder because you could that a territory is being taken, but not see where the person is.

i've crouched and hidden while taking a territory and watched an enemy come up and not see me and i just pop him in the back of the head.

makes it harder to defend though too because you can find them as easy. i usually lob a couple of grenades on the flag and that flushes them out a bit.
