army; armed forces
“Une doctrine militaire est constituée des principes fondamentaux selon lesquels l'armée ou certaines de ses parties accomplissent leurs tâches pour atteindre les objectifs nationaux.” — Military doctrine is made up of fundamental principles according to which the armed forces, or certain parts of them, perform their duties in order to achieve national objectives.
Inherited from Middle French armee, from the feminine past participle of the verb armer; first attested in French circa 1370 (except in Anglo-Norman), borrowed through Anglo-Norman from Medieval Latin armāta (“armed force”), the neuter plural form of the past participle of Latin armō (“to arm”), from arma (“arms, weapons”), from Proto-Indo-European *h₂(e)rmos (“fitting”), from the root *h₂er- (“to join”). Doublet of armada, a borrowing from Spanish. Displaced Latin exercitus (“army”).
