JP Johnston - GOs are also used to award Good Conduct Medals (these contain a lot of names, serial #s etc) marksman test results by name also a lot of names, and Purple Hearts. These may be one name only or many.
They are held at the National Archives (NARA). To receive a copy NARA will need the year and date as well as the unit issuing the GO.
Send a detailed request (GO#, unit name, date, soldier's name) to firstname.lastname@example.org.You will receive a message that they have your e mail and instructions. Mary
