Nearly all military vehicles- armored tankers, missile submarines, fighter jets have come equipped with GPS tracking devices. Even US military, air force and navy officers are often planted with tracking devices to monitor asset's movement, locate exact location and ensure safety.
Citizen safety is a primary government concern. This is why it is important to keep track of assets under its control; including ambulances, fire trucks, police cars and other emergency service vehicles and staff. Quick responses to emergencies make for a safer community.
