means The highest army rank in many countries, typically a five-star-level title awarded to top generals, often for major military leadership rather than battlefield combat itself.

from A marriage of two old job titles: 'field,' meaning open battleground, and 'marshal,' which traces back through French to a Germanic compound roughly meaning 'horse servant' or 'stable keeper' — someone who managed the lord's horses. Over centuries that lowly stable hand's title climbed the ranks of European courts and armies, eventually attaching itself to 'field' to describe the officer who commanded troops in open battle, and later became a largely ceremonial peak rank rather than a working battlefield post.
