What describes the collar device for an E-9 in NJROTC?

The collar device for an E-9 in NJROTC is represented by an eagle and two stars perched on a fouled anchor. This insignia symbolizes a high rank, denoting the senior enlisted status within the Naval Junior Reserve Officer Training Corps (NJROTC). The eagle signifies sovereignty and the authority of the position held, while the fouled anchor represents the naval service and tradition. The addition of two stars illustrates the distinction and level of achievement associated with the E-9 rank, indicating significant experience and leadership capabilities.

In contrast, other options depict variations of insignia that are related to different ranks. For instance, one option features an eagle with just one star, which corresponds to a different enlisted rank. Similarly, an eagle perched above a fouled anchor is a design associated with an even lower rank. Therefore, the specific combination of an eagle and two stars perched on a fouled anchor is what accurately defines the collar device for an E-9 in NJROTC.
