Base Alert Codes.

Just a small idea.

Black: Attack possibly imminent.
Red: High Alert.
Yellow: Be on your feet.
Green: Everything normal.

Basically, Put a Small rectangular board up in the base, and depending on the current situation we colour it accordingly...

I like it, make a designated spot, and use the color tool + a prop for the board.

Ive got to actually get TT first :P

Well its what british military bases do, so i thought it would be a good idea :)

Good idea, a camera could be used to so you can possibly place multiple boards, and colour them using the cameras.

Would be easier for all to see.
