Plural of cavalry, meaning soldiers who fight on horseback or modern soldiers in armored vehicles.
From Middle French 'cavalerie' (horsemanship), derived from Old Italian 'cavallo' (horse), which comes from Latin 'caballus' (horse).
The term 'cavalry' originated from elite mounted warriors who dominated battlefields for over 1,000 years—even today we keep the name for armored vehicle units, honoring that history of mounted mobility.
