Strategy

 * Alpha Fenrir are mostly invisible and therefore not directly targetable by towers and units. However, if area damage is unleashed and they are caught in the radius they will still take damage. Dropguns can be used for this purpose.
 * In packs, alphas gain immunity to fleeing when lit on fire. It seems counterintuitive to use flamewalkers against them as they will be the almost always be the last survivors of the pack. However, flamewalkers are still viable, albeit not as great.
 * Brawlers, with their high concentrated attacks will deal with alphas quite nicely. However, make sure to get rid of most or all regular fenrir otherwise they will be overwhelmed.
 * Guardians are also great for the same reasons as brawlers. They can be paired with diplomats to stun alphas, which also momentarily prevents them from going invisible.
 * Alpha Fenrir follow the same mechanics are regular Fenrir, they will attack Raad that are closer. As such, you can utilize them to wreak havoc on Raad enemies.

Trivia

 * Alpha Fenrir may be seen as similar to the alphas of wolf packs in real life. However, this is a common misconception, wolf packs in real life do not actually have alpha leaders. Alphas are actually just parents or breeders of young wolf pups, and not dominant figures in a pack.
 * Fenrir are based off of Norse Mythology. In the Norse myth, Fenrir is a giant, monstrous wolf that is a Jötunn. The Fenrir in Iron Marines are much smaller than Fenrir in the myth.
