         reference to the operations and equipments of an army
         during a campaign away from permanent camps and
         fortifications. In most cases such use of the word is
         sufficiently clear; as, field battery; field
         fortification; field gun; field hospital, etc. A field
         geologist, naturalist, etc., is one who makes
