The Government Operations Centre runs constantly. It's 24/7 to begin with, but it constantly runs exercises and is part of exercises, running drills. For example, with regard to the air incident protocol, which is a protocol for the government to respond to air threats, they sometimes run up to two or three drills a week in just exercising—constantly exercising.
As most of us know, in policing, law enforcement, security intelligence, or a military environment, the key to a response is exercise.
