If you're playing on a server with TG, please be in TS.
We've had several friendly-fire kills over the last couple of days. Standard SOP to avoid that is:
1. Be in TS if you're playing with TG.
2. When someone calls out "Prone Check" - press z to get prone.
This'll ensure you don't get shot in the face by a friendly. This game is pretty unforgiving and there's no time to second-guess if someone is friend or foe -- please, please be sure you're with us and paying attention to prone checks.
