Harford County northeast of Baltimore hosts Aberdeen Proving Ground — the Army's oldest active proving ground and the home of Army research development and test and evaluation for all ground combat systems. APG also hosts the Army Cyber Center of Excellence and Chemical Corps school. The Susquehanna River and its tributaries create flooding risk. Ida in 2021 caused flooding across the county. The county has significant military heritage from the War of 1812.
