If you don't know where Tenino, Washington is, where should you ask your fellow Cadet to look for the correct Map Sheet Number?

The correct answer is to refer to the Adjoining Map Sheets Diagram because this resource is specifically designed to help locate map sheet numbers associated with various geographic areas. The diagram provides a visual representation that shows how different map sheets are connected, making it easier to identify the correct sheet for a specific location like Tenino, Washington.

Using the Adjoining Map Sheets Diagram allows cadets to quickly navigate through related maps and find the relevant sheet without much searching. This method is particularly useful for those who are familiar with map reading, as it can save time and effort when looking for a specific area.

Other options, like Google Maps, while useful for finding general directions or locations, do not specifically provide information on map sheet numbers used in military or geographical contexts. The City Directory typically focuses on local businesses and addresses rather than geographical map references. The Topographic Map Index may offer an overview but may not be as directly helpful as the Adjoining Map Sheets Diagram when trying to locate a specific map sheet for an area like Tenino.
