Aberdeen Proving Ground
First officially used on October 20 1917, Aberdeen Proving Ground is the United States Army's oldest active ordinance and tactics testing facility. A large amount of equipment and materials ubiquitous to the United States military in World War Two and beyond first underwent testing by the Army at the proving ground before its general adoption.
Bates, Bill. Aberdeen Proving Ground. Arcadia Pub., 2007.
This is an detailed overview of history of the proving grounds. The text covers the history of the site from around its inception until the end of World War II. The authors Bill Bates and retired Major General John Doesburg are suited to retelling the history of Aberdeen. Mr. Bates in particular compiled the series Images of America, which covers numerous different topics of United States history, and Major General Doesburg’s authority on the topic is clear. The information in the book remains accurate, but does not cover more recent history.
