What information is typically embossed on identification tags, also known as dog tags?

Identification tags, commonly known as dog tags, are an essential piece of military identification and contain vital information that serves multiple purposes, primarily identification in the event of injury or death. The correct choice highlights the information typically embossed on these tags, which includes the service member's name, social security number, branch of service (in this case, USN for United States Navy), blood type, and religious preference.

This information is crucial for several reasons. The name and social security number ensure accurate identification of the individual, which is particularly important in situations where personnel records need to be accessed quickly. The branch of service indicates the military organization to which the individual belongs, which is important for organizational and logistical purposes. Blood type information is critical in emergency medical situations, allowing medical personnel to provide appropriate care without delay. Religious preference can aid in the provision of last rites if necessary and respects the individual's beliefs.

Including details like age, place of birth, medical history, or emergency contacts on dog tags is not standard practice, as this information could lead to privacy concerns and is typically maintained in personnel records separate from combat readiness. Hence, the correct answer encapsulates the precise and standardized information required for effective identification and medical response in a military context.
