FamilySearch Indexing: US—Registers of U.S. Army, 1798-1913, Project Updates
Military Rank - Hidden Field: We not longer index the military unit. If you have a batch that was indexed before the change, the field will be hidden and you will need to unhide the field and carefully arbitrate it. It can be unhidden in two ways:
1-Click View/Organinze Fields and unhide the field or
2-Try to submit the batch. This will unhide the field.
