2-91. Company-size combat units can fight together or as subordinate platoons. Cavalry troops frequently operate with their platoons in separate areas. In combined arms battalions, companies either fight as organic units, or they are task-organized. A company team is a combined arms organization formed by attaching one or more nonorganic armor, mechanized infantry, Stryker, or infantry platoons to an armor, mechanized infantry, Stryker, or infantry company, either in exchange for, or in addition to, its organic platoons. These company teams can include other supporting squads or platoons, such as engineers. Company teams are task-organized for specific missions. Company teams can match capabilities to missions with greater precision than units using only organic platoons. However, the attachment of different units at the company level demands thorough training to achieve the maximum complementary effects. Whenever possible, platoons and detachments train together before their commitment to actual operations.
