Guardians: Marvel Cinematic Universe
SHIELD maintains a number of alert codes for the Guardians. Each of you has access to a pager, and app on your smartphone, or some other means of being contacted 24/7. I will assume you always have this method available unless I or you explicitly say otherwise. The codes are:
Code Red – Imminent or ongoing internal threat (i.e. an attack in progress on your base or team). Attempt to rally on a leader or otherwise defend in place. Break cover as needed, but be aware of cover as a defense.
Code Blue – Imminent or ongoing external threat (i.e. an attack in progress on the city or in the city). Call in for instructions, rally at base as a default. Break cover as needed.
Code Orange – Urgent external threat. Call in for instructions, rally at base as a default. Break cover only if instructed.
Code Yellow – Guardians report to base. Do not break cover.
Code Green – Allied or neutral operation in progress in the local area. Increase situational awareness to avoid friendly fire incidents.
