The Doorkickers Real Time Strategy (RTS) video game made by Killhouse Games, is now available on Steam... "Door Kickers is an innovative realtime strategy game that puts you in charge of a SWAT team and lets you command them during a tactical intervention. Analyze the situation, plan team routes, choose equipment and breach points and coordinate multiple troopers to reach the hostage room before the bad guys get to press that trigger."

The Red Rag, otherwise also known as the Dead Rag, is now gathering steam for more widespread adoption outside of the USA where it is already a common thing as a hit marker rather than always shouting that you're hit on your way to the regen zone, or for a medic to easily spot you. It is such a lowcost piece of cloth that  you can put on your rifle or your head rather than strain your arm as it's constantly raised.
