Drake is a Green Earth CO with sturdy Naval units and strong CO Powers, but has the worst Air units in AWBW.
Day-to-day Effects: All of Drake's naval units have 25% increased defense and +1 Movement, but all of his Air units have 20% decreased offense. Drake's movement is not hindered in Rainy weather, and it is more likely to rain if Random Weather is enabled. This modifier stacks, so the more players controlling Drake in given a game, the more likely it is to rain.
Power: Tsunami -- All enemy units lose 1 HP (but will not fall below 0.1 HP displayed as 1) and half of their fuel (rounded down). All of Drake's units gain 10% increased offense and defense.
Super: Typhoon -- All enemy units lose 2 HP (but will not fall below 0.1 HP displayed as 1) and half their fuel (rounded down). The weather changes to Rain for one day, and all of Drake's units gain 10% increased offense and defense.
Drake is perfectly equipped to dominate sea battles and tends to be almost broken on island-hopping and heavy naval maps. Outside of that, his only saving grace is in his bland 100/100 land units and his powers.
In maps with no naval units, or ones where the only viable naval units are transports, Drake will have to use every land-based tactic in the book to gain an advantage over any other CO. Stay away from deploying 80/100 air units, they're too weak to be of any decent use. (You will find it very hard to get copter + tank two-hit KOs, especially vs 100/100 tanks on cities)
It is recommended to use his CO powers upon getting sufficient charge; this will help you get more kills on enemy units, as well as preventing the enemy from killing yours. Picking Drake on larger maps will let you get more Tsunamis and Typhoons off, making your life easier.
