Which term is used to refer to several sections or elements that fall under a squadron?

The term that refers to several sections or elements that fall under a squadron is "Flight." In the context of military organization, a squadron is typically composed of multiple flights, which are smaller units that can operate independently but are still part of the larger squadron structure.

A flight usually comprises several elements effectively organized to fulfill specific missions or functions. This structure allows for more manageable command and control, as well as better operational efficiency. While terms like team, section, and unit have their own meanings within military hierarchy, "flight" specifically describes a subdivision of a squadron, establishing a clear relationship in the hierarchy and organization of military forces.
