If you have Excel, v2013-2016 I think, you can map your data that is in a spreadsheet. You just need data in Lat/Lon pair, City, Country/Region, Zip/Postal code, State/Province, or address. Go to Insert, Map, Launch Power Map, click New Tour. Search the web on Power Maps for Excel for tutorials. You can use different column values for attribution, e.g., Unit Name, Mission, Count of Days Deployed, Number of Half-Norwegians, etc. This would need to be unclassifed data, btw. Also applies to ArcGIS.com.
