battlefield-3
Playing around in Battlefield 3 I often see players (with a rank higher or equal to 42, I noticed) that wear a black suit that's very difficult to spot (i.e. a relatively long time and short distance before the orange triangle appears over the player's head).
Is it part of some expansion or does one obtain such camo at some rank? I can't find any clue about it.
There is an anti-team-killing setup on the server side of things. Server admins can adjust these as they see fit, but if you team kill enough you'll get booted.
This is what the defaults look like:
If you go to your profile (not your stats pages, but your user profile), the second "section" down will show your last 16 battle reports, I haven't been able to find a way to see older reports.

Spec Ops camo is unlocked at level 42.
It doesn't have the special properties you listed (that being harder to spot for your teammates) it does however have the special property of making you harder to see if your enemy is using an IRNV scope.
While wearing it, the black parts of your camo (not your gun or the ammo pouches etc.) will not show any heat through an IRNV scope.
