Call of Duty: Modern Warfare 3 introduces a new type of campaign level known as Open Combat Missions. These levels take the familiar linear and cinematic Call of Duty mission and turn it on its head, becoming more open and giving the player the freedom to approach objectives in different ways. In each of these missions, there are Supply Boxes with weapons and Field Upgrades that you can collect to expand your arsenal for that level. Collecting every weapon and item from these Supply Boxes in every Open Combat Mission will unlock the Gearhead Achievement and Trophy. In Mission 10: Highrise, Gaz and Price target Markarov’s second-in-command, Andrei Nolan. This guide will show players where to find all Supply Boxes with Weapons and Items in Mission 10: Highrise in Call of Duty: Modern Warfare 3.

All Highrise Supply Box Locations In Call of Duty: Modern Warfare 3
There are a total of 19 Supply Boxes found in Mission 10: Highrise in Modern Warfare 3, including 17 unique weapons and 2 Field Upgrades. When a player looks at their TacMap, all of the locations will be marked by a gun icon or a gear icon for Weapons and Field Upgrades, respectively, when the Supply Box is opened. Upon discovering a Supply Drop for the first time, it will be marked on the map with a gold case with a question mark in the center. These cases can be discovered in any order but there will be a lot of directing around the level with references to previous Supply Boxes thanks to the many different paths and levels available in the mission. Below is the breakdown of where to find all the weapons and items in Mission 10: Highrise in Modern Warfare 3.
