Which of the following identifiers is for a military airport?

The chosen answer, which indicates that none of the identifiers provided correspond to a military airport, highlights an important aspect of airport coding conventions. In the United States, military airports typically do not use the standard public use airport identifier format that begins with the letter "K." The identifiers starting with "K" are primarily allocated for civil airports located in the continental United States.

Furthermore, identifiers beginning with "S" generally correspond to airports located in South America or specific civilian airports in various regions, while "D" indicates that none of the provided identifiers match military airport coding. This reinforces the point that military airports often have different coding systems which may not strictly adhere to the ICAO or FAA identifier guidelines that apply to civil airports.

Understanding these coding conventions is essential for recognizing and navigating among various types of airports effectively.
