These missiles are for use with the Ke-M2 "Mindy" Series of Power Armor.
While the Countermeasure Augmentation Pods are useful for distracting enemy missiles or baffling sensors for a few vital seconds; a few vital seconds may not be enough in some circumstances. Misdirection Countermeasures take a different approach; they're decoys, small devices that emit a sensor signature on par with a Mindy armor. While less useful at close range (where visual confirmation can easily show the pods as false) when fighting at extreme distances, an enemy that suddenly sees two (or more) identical sensor signatures is suddenly far less likely to shoot at the right target.
Note: if loaded into the Countermeasure Augmentation Pods, there is space for only 30 missiles so some others (SDMM, MFMA, ARMA or a combination of them) must be removed to make room.
