Olaf

Army: Blue Moon
CO Power Requirements: three stars for normal, then four more stars for super.
CO Power: Blizzard--Causes snow to fall, which adversely affects all units except his own.
Super CO Power: Winter Fury--A mighty blizzard reduces enemy movement and causes two hit points of damage to all deployed enemy troops.

Olaf's special powers cause a one-day snowfall, which reduces the power of enemy units and inhibits their ability to move. Enemy vehicles won't be able to move more than two spaces, while infantry are limited to one during the snowfall. Olaf's own units retain their normal movement privileges and are bolstered in combat.

Grit

Army: Blue Moon
CO Power Requirements: three stars for normal, then three more stars for super.
CO Power: Snipe Attack: Increases range of distance weapons by one space. Attack strength of these units also increases.
Super CO Power: Super Snipe: Distance weapons can shoot two spaces farther than normal. They also receive a firepower bonus.

The range on Grit's distance weapons is one space greater than the indirect-fire units of other COs. They cause more damage, too. Grit is weak in direct combat, though. His infantry and direct-fire units are reduced in strength by 20%; indirect-fire unit power is increased by 10%, along with the extra attack range. Super snipe, Grit's super CO power, nearly doubles the attack power of his indirect-fire units.

Colin

Army: Blue Moon
CO Power Requirements: two stars for normal, then four more stars for super.
CO Power: Gold Rush--Increases deployment funds by one and a half times.
Super CO Power: Power of Money--Uses wealth to increase the strength of weapons. The more funds available, the stronger the weapons become.

Colin is the heir to a vast fortune, and he purchases all units at a special low price. His troops' low firepower stems from his lack of experience. All of Colin's default units are reduced in power by 20%--but they are also 20% cheaper, so he can have more deployed.
