An army is an organized group of fighters, especially a country's official military force. When a country goes to war, it sends an army to fight.

An army is typically defined as fighting on land, while a navy battles at sea, and some countries make this even more clear by distinguishing their "Land Army" from their "Air Army." The 14th century meaning of army was "armed expedition," from the Old French armée and the Latin root armata, "armed, equipped, or in arms."
