This applies to any semi serious shooter
1: YOU ARE NOT FUCKING RAMBO SO STOP TRYING TO BE RAMBO!
2: Do not pull the pin on your grenade and then proceed NOT to throw it
3: If you are planting any kind of high explosive TELL YOUR TEAM
4: Aim for the chest and stomach, easier to hit then the head and a couple of bullets will generally kill
5: If you are moving in front of a machine gun or other rapidly firing weapon tell the operator
