In wartime, monitoring an adversary's communications can be a valuable form of intelligence. Consistent call signs can aid in this monitoring, so in wartime, military units often employ tactical call signs and sometimes change them at regular intervals. In peacetime, some military stations will use fixed call signs in the international series.

“His ugliness was the stuff of legend. In an age of affordable beauty, there was something heraldic about his lack of it. The antique arm whined as he reached for another mug. It was a Russian military prosthesis, a seven-function force-feedback manipulator, cased in grubby pink plastic.”
—William Gibson (b. 1948)
“The poet alone knows astronomy, chemistry, vegetation, and animation, for he does not stop at these facts, but employs them as signs. He knows why the plain, or meadow of space, was strewn with these flowers we call suns, and moons, and stars; why the great deep is adorned with animals, with men, and gods; for, in every word he speaks he rides on them as the horses of thought.”
—Ralph Waldo Emerson (1803–1882)
“They lock me in this chair at eight a.m.
and there are no signs to tell the way,
just the radio beating to itself
and the song that remembers
more than I.”
—Anne Sexton (1928–1974)
