Getting hold of the Ammo Mod Circuit Boards in the mission Automated Backup of Modern Warfare 3 Zombies can certainly be difficult. Here are some areas where you can find them:

• Aether Nests
• Infested Strongholds

Infiltrate these locations and proceed to eliminate all the enemies. These areas are often infested with deadly zombies and toxins. Hence, before heading in, make sure that you aren't low on essential resources such as ammo, Gas Masks, and shields.

Once the area is clear, loot the various caches within, especially the Purple Aether Caches, to find the Ammo Mod Circuit Boards.

Please note that the generic Circuit Boards that you can find in loot boxes won't count. This mission specifically asks you to find the ones with the ammo mods.

After installing all three Ammo Mod Circuit Boards on three different turrets, the mission will be complete, and you will instantly earn the rewards that this mission promises.
