What insignia indicates that a ranking official is a commander?

The star insignia is utilized to signify the rank of a commander in various organizations, including military and law enforcement contexts. This symbolism stems from a long tradition where stars often denote authority and leadership roles. The presence of stars in rank insignia represents a higher level of responsibility and command, differentiating it from lower ranks which may have other symbols.

In contrast, the spread eagle insignia typically represents national loyalty or authority and is more commonly associated with certain staff positions rather than command. Similarly, a ball insignia can signify different roles depending on the institution but does not specifically represent a commander. The flat truck insignia is not traditionally recognized as a standard insignia for command roles and likely refers to a niche or specific context unrelated to rank designation.
