Communication Challenges During General Quarters
Voice communication being the first choice in transmitting orders, the noise and confusion of battle or an emergency situation may restrict its use and effectiveness. Modern-day ships have radio, electronic, light systems, telephone and computer-based technology that greatly enhance communication, but there is also the possibility that any or all of them could be damaged, disabled, out of commission, unavailable or blocked due to the exact battle condition or emergency at hand. Likewise, noise, enemy jamming, enemy interference, electronic pulses emitted by certain types of munitions, and other liabilities hamper communication. Darkness, heavy smoke, fire and lack of line-of-sight prevent it, but in situations of clear or adequate visibility, and when crewmembers can see each other, hand signals are effective, and flashlights are options, too. Whistles and Morse code (tapping) are other audible options, and can be used in innovative and imaginative ways.
Coordination with other friendly ships in the immediate vicinity, friendly aircraft in the immediate vicinity, with higher command, and with shore-based units must be done, especially in the event of enemy attack or a devastating storm at sea. When operationally prudent, the ship's location at the start of GQ should be transmitted to higher headquarters, other friendly ships and aircraft, in the event that communication or visual contact is lost. Usually, if one ship in close proximity to other friendly ships goes to GQ, all of the others will do the same, for the same threat may exist for them all.

Famous quotes containing the words challenges, general and/or quarters:
“A powerful idea communicates some of its strength to him who challenges it.”
—Marcel Proust (1871–1922)
“All the critics who could not make their reputations by discovering you are hoping to make them by predicting hopefully your approaching impotence, failure and general drying up of natural juices. Not a one will wish you luck or hope that you will keep on writing unless you have political affiliations in which case these will rally around and speak of you and Homer, Balzac, Zola and Link Steffens.”
—Ernest Hemingway (1899–1961)
“The supreme, the merciless, the destroyer of opposition, the exalted King, the shepherd, the protector of the quarters of the world, the King the word of whose mouth destroys mountains and seas, who by his lordly attack has forced mighty and merciless Kings from the rising of the sun to the setting of the same to acknowledge one supremacy.”
—Ashurnasirpal II (r. 883–59 B.C.)
