The standard armor (known as security armor in the manuals) is an item that appears in the Doom games as a bright green military vest, similar to the one worn by the player sprite. When collected, it increases the player's armor percentage to 100. It cannot be collected if the player already has at least 100 percent armor. When an armor is obtained, the game displays the message: "Picked up the armor.", an unusual format compared to the rest of the non-weapon pickups.

The armor will absorb one-third (⅓) of all damage received, rounded down, until it is fully depleted.

This item is not counted in the items percentage displayed at the end of each level.
