In the past decade, a new wave of commercial ARVs specifically built for law enforcement has hit the market. Few agencies could afford these big-ticket items prior to then, so initially the expense made it slow-going for the police armored vehicle industry. Then 9/11 changed law enforcement's attitude, and the formation of the Department of Homeland Security and its grant programs led to unprecedented funding for local law enforcement equipment, including ARVs. Responding to this increased demand, ARV manufacturers are developing the next generation of ARVs to meet the needs of contemporary tactical officer.
