Heavy impact plating

Heavy Impact Plating (also known as Heavy Blast Armor) is a type of body armor system used by UNSC Soldiers and Marines. It is worn over the wearer's camouflage utility uniform, and is composed of metal segments that bulwark everything vital from the neck to the knees.

Impact plating was usually not worn for rapid, airborne strikes, but SSgt Avery Johnson and SSgt Nolan Byrne were ordered to wear impact plating on their assault on an Insurrectionist bomb-shop on Tribute.

Impact plating is impervious to light handheld firearms such as Automatic Pistols.
