Destroying the Mercenary Convoy
An RPG weapon is the easiest way to destroy these mercenary Convoys in MW3 Zombies. Initially, we tried to complete the mission a couple of times with some other weapons, but the RPG provided the most efficient results. So, make sure to bring down enough ammunition for it.
There will be a bunch of soldiers in these vehicles, and you have to eliminate all of them. Once you destroy them, you will find a Mercenary Stronghold keycard from one soldier. Some players mentioned the last soldier dropped the keycard. But we can’t guarantee that since we started the search for the keycard after eliminating all soldiers.
Also, destroy at least one convoy to complete the mission. Then, you will complete the mission and receive the Bone Rattle weapon blueprint and 3000 XP as rewards.
