The Anchorage Armada should use "Warrior Song - Leviathan" by Sean Householder. It is inherently noble to risk everything, from your health to your life, to fight in service of your country. For a military town like Anchorage, which has the highest amount of army veterans in the USA, I think it would be more than appropriate to use this as their song. Not only that but the lyrics can also be used to discuss the Armada's history in the league:

Forged in the fire lit long ago
Stand next to me, you'll never stand alone
Last to leave but the first to go
Lord Under Weigh is the only way I know

This could be used in reference to how the Armada started as the Prince Albert Firebirds and how the Armada reflects the nature of the city they call home. No excuses for anything, no training session or game. If you are an Armada player and you stand with your fellow men, you will never stand alone
