Wearing armor can help give you the edge in any fight by absorbing damage or preventing you from getting hurt. With the exclusion of Cyber Armor, (which adds both Physical Defense and Physical Attack bonuses) Armor adds bonus mods to Physical Defense (PD) scores. These mods are automatically calculated into your rolls when you "wear" the armor by loading it into your HUD and selecting it. This activates the item and the HUD includes the applicable modification bonus. Only one armor type may be selected and worn at one time, such as one helmet, or one type of Body Armor.
