field marshal

Synonym discussion
Sense: noun/1
These three words all point to people at the top of an army, but they sit at different levels. A 'field marshal' is a fixed rank and the highest one a British army officer can hold, above every general; it is rare and often given as an honour late in a long career. A 'general' is also very senior and may command large forces, yet still ranks below a field marshal. A 'commander-in-chief' is different again: it names whoever is in overall charge of the armed forces at a given moment, which in many countries is a political leader such as the president, not a career soldier. So a general can be promoted to field marshal, but a commander-in-chief is usually a role, not a step on the military ladder.
Common collocations
Etymology
The phrase joins 'field', meaning the open ground where battles were once fought, with 'marshal', a word that began as a title for someone who looked after horses and later came to mean a high officer who organises an army. Put together, the term came to name the officer who directs forces in the field, and over time it rose to mean the very highest army rank.
