How to Find and Destroy a Mercenary Convoy in MW3

The elusive Mercenary Stronghold Keycard is one of the most coveted items in Call of Duty: Modern Warfare 3’s Zombies mode. This rare keycard grants access to the formidable mercenary strongholds scattered across the zombie-infested maps, offering brave undead slayers lucrative opportunities if they’re up for the challenge.

Locate and Secure a Mercenary Convoy

Before you can get your hands on that precious keycard, you’ll need to track down and remove one of the deadly mercenary convoys patrolling the maps. This is no easy feat, as these mobile squads are heavily armed and ready for combat. Here are some tips for locating and safely engaging a convoy:

The best approach is to actively search while playing strategically. Listen for your AI teammates calling out convoy alerts, and keep an eye on your minimap for groups of red vehicles driving together. Convoys typically move along significant roads and periodically sweep hotspots like the central highway and zone borders.

Once you’ve spotted a target, thoughtful preparation and careful execution are key. Gear up with your most potent weapons and equip valuable perks like Juggernog for added health. Move to intercept the convoy in an area that provides good cover or choke points to limit mobility.

To initiate the attack:

  1. Stay mobile and use explosives to soften them up before focusing fire.
  2. Coordinate with teammates to divide mercs’ attention.
  3. Prioritize drivers and heavy gunners first before cleaning up the remaining forces.

You’ll take down the convoy with persistence and sharp tactics and claim that valuable keycard!
