The Odyssey
(Edited)

Let me tell you—so help me it's the truth—
if he sets foot in King Odysseus' royal palace,
salvos of footstools flung at his head by all the lords
will crack his ribs as he runs the line of fire through the house!
p. 361.8

salvos = thrown projectiles
At his command,
concentrating their shots, all six hurled as one
but Athena sent the whole salvo wide of the mark—
one of them hit the jamb of the great hall's doors,
another the massive door itself, and the heavy bronze point
of a third ashen javelin crashed against the wall.

salvo = fired arrows
And again the suitors hurled their whetted shafts
but Athena sent the better part of the salvo wide—
p. 447.9

Definitions:

(1) (salvo as in: a salvo from the guns)
a rapid discharge from one or more weapons
(2) (salvo as in: a verbal salvo)
a sudden, forceful attack in words or actions
(3) (meaning too rare to warrant focus)
Much more rarely, a salvo can reference a sudden burst of applause or cheers as in "There was a salvo of approval."

Even more rarely, salvo can reference an excuse or something to make someone feel better about their self-image as when Henry Fielding wrote, "Blifil had nothing more to do than to confirm these assertions; which he did with such equivocations, that he preserved a salvo for his conscience; and had the satisfaction of conveying a lie to his uncle, without the guilt of telling one."
