armored

An armored vehicle or person is protected by strong metal covering for safety.

The word "armored" is often used in military contexts to describe tanks and other vehicles that are designed to withstand damage from enemy fire. For example, you might hear about a heavily armed and armored tank that was deployed on the battlefield. You can also use "armored" to describe people who work with these vehicles, such as soldiers wearing protective suits to shield themselves from harm. In some cases, you'll see armored cars or buses driving around cities with reinforced steel plating to protect against robbery or attack.
