Call To General Quaters
Or Call To Battle Stations
General Quarters or Battle Stations is an announcement made aboard a naval warship to signal the crew to prepare for battle.
When the call to General Quarters (GQ) is made, the crew prepares the ship to join battle. Off-duty or sleeping crewmembers report to their stations and prepare for action. Watertight doors between bulkheads are shut and security is increased around sensitive areas such as the bridge and engineering rooms.
