An Army is a term either referring to one of the largest types of formation for a land-based military force, or the entirety of a nation's military force responsible for its land defenses, both of which are composed of soldiers, trained to engage in war.
An army, as a single in-theater force, operates at a strategic level, but is composed of smaller operational units which operate at at the level of operational art or tactics.
In modern warfare, a field army is an echelon above corps, but usually more an administrative than operational headquarters. It is unlikely that multiple field armies will ever be in battle, but, in the Second World War, army groups were operational headquarters for multiple field armies.
Not all countries use "army" to indicate the same level of command. Western practice is that a field army is made up of two or more corps, and is commanded by a full general or lieutenant general. WWII Japanese "armies" were of several levels; an unqualified "army" was equivalent to a Western corps, an "area army" to a field army, and a "general army" to an army group.
