What device represents a Petty Officer Second Class (PO2)?

The emblem that signifies a Petty Officer Second Class (PO2) is represented by one eagle above two chevrons. This designation is part of the U.S. Navy's enlisted rank insignia system, where each rank has a specific combination of insignia elements that indicate both the pay grade and the level of responsibility associated with that rank.

In this case, the one eagle represents the rate of Petty Officer, while the two chevrons denote the second class rank within that category. The combination effectively communicates the rank of PO2 visually, making it easily recognizable among personnel and during inspections.

Other options such as the gold fouled anchor with "USN" or the one eagle above three chevrons represent different ranks within the Navy, while two diagonal bars typically indicate a different classification entirely, further underscoring why the chosen answer accurately reflects the insignia for a Petty Officer Second Class.
