Red vs. Blue centers on the Red and Blue Teams, two groups of soldiers engaged in a supposed civil war. Originally, each team occupies a small base in a box canyon known as Blood Gulch. According to Simmons, one of the Red Team soldiers, each team's base exists only in response to the other team's base. It is later revealed that there is no actual civil war; both the Red and Blue armies are under the same command, Project Freelancer, and only exist as training simulations for Freelancer Agents. Although both teams generally dislike each other and have standing orders to defeat their opponents and capture their flag, neither team is usually motivated to fight the other (except for Sarge, the head of Red Team). The Red vs. Blue storyline so far spans fifteen full-length seasons and five mini-series. Rooster Teeth periodically releases self-referential public service announcements and holiday-themed videos, which are generally unrelated to the main storyline and not considered canon. In these videos, the members of both teams are actors who claim to be from Red vs. Blue.
