While on board the Harry S. Truman last year, I got to witness a common but very important training event, conducted by the crew-- a GQ Drill (General Quarters).
"General Quarters" is regularly sounded to keep the crew sharp, and on their toes, ready for any contingency. Every crewman has a duty station when this happens, and they all rush to their battle stations, put on their gear, and do drills. It's a very interesting thing to watch, and it makes you admire the efficiency and teamwork the Navy engages in with every sailor and section on board a naval vessel.
Getting geared up fast for fire control...
