While progressing through the campaign ofCall of Duty: Modern Warfare 3players will have to scavenge for weapons and equipment in six of the fourteen missions. These Open Combat Area missions, as the game calls them, will drop players into an unmapped area and require the area to be searched for supply crates,armaments (known more commonly as killstreaks), and equipment like plate carrier upgrades. When players find the plate carrier upgrades they will expand their armor vest adding a plate slot.

Players will start the mission with a single plate slot in their vest and can find two plate upgrades on each Open Combat Area mission. If players can find all twelve plate upgrades they will unlock the Bulletproof Achievement on PC and Xbox or the Bulletproof bronze trophy on PlayStation.
