Which of the following is NOT one of the nine parts of the ATO coat of arms?

The crown is not one of the nine parts of the ATO coat of arms. Understanding the structure of the coat of arms is crucial to identifying its components. The ATO coat of arms consists of several specific elements that follow heraldic conventions, which include a crest (the topmost part), a shield (the central part that displays the main design), and a pale (a vertical band that can denote various meanings in heraldry).

In heraldry, each part has its own significance and role within the composition. The crown, while often associated with royalty or authority, does not specifically belong to the standard components of the ATO coat of arms, which focuses on elements more directly related to the organization's identity and values. This distinction is key for understanding the formal representation of the ATO and helps reinforce the correct attributes associated with its coat of arms.
