Footnotes

1. Source: Robert Livingston. Robert derived his information from a paper available on microfilm at the Patton Museum (curator Charles Lemons). This criteria is known as the ‘Navy Limit’ but it applies to the testing of weapons of any service arm. There are other criteria, used for purposes other than the testing of gun penetration, known as the ‘Army Limit’ and the ‘Protection Ballistic Limit’. [up]
