The Ground Launch Sequencer Engineer is responsible for monitoring the operation of the automated Ground Launch Sequencer system, which controls the countdown from T-9 minutes until launch. After this point through to T-31 seconds, they are in charge of implementing a manual hold if necessary. After T-31 seconds however only cutoff is available and will result in a recycle of the countdown to T-20 minutes and a scrub of the launch. The request for a cutoff is phrased "CGLS, give cutoff."
