CONCORD is one of several policing forces in High Security Space (0.5 to 1.0 security status), tasked with eliminating the ships of players that have illegally attacked other players. Such as attacks that result in the players receiving an active Criminal Timer in High Security Space.
While CONCORD forces do react quickly and with force, they do not have a mandate to protect attacked players and as such will not necessarily be able to prevent eventual losses if attackers can field sufficient firepower to destroy their targets before CONCORD can intervene. CONCORD should therefore be regarded as a force of retribution, not one of protection.
