General Tips when starting out:

Team Kills happen, in the heat its hard to distinguish units, it doesn't happen often but when it does just say sorry to the team mate you shot and usually every time your forgiven. I haven't ran into all that much Salt.

When you use a LAT (light anti-tank) or RPG, please, call out back blast be fore you fire at least twice, or check your map... You never know if a medic or a fellow team mate is starring into the exhaust barrel of your weapon. Deaths can and have happened, this by far other then grenades will be your highest risk to be the Team Killer or to be the TK.

If your a medic, and your in an active fire zone (i.e. bullets are snapping) announce your actions over mic. This will hopefully avoid pre-mature "give-ups" or deaths involving ticket loss. This could also help organize covering flanks for team mate recoveries.

Simple to remember, a Vehicle is NOT a knife.... (keep distance unless advancing with foot soldiers)
