The "Easy" difficulty level indicates that the human who set-up the game wants your AI to behave like a punch bag.
On Warzone 3.2 and above, EASY AIs receive a hard-coded penalty that makes them produce 25% less oil.
As such, your AI should act like a n00b:
Use a nonsensical build order (build HQ, power gens and oil derricks at the start)
Use a nonsensical research path (research random things if possible)
Use badly designed droids, attack in single unit or small groups
Don't micro-manage units
Turtle a bit
Basically, do all the wrong things. In many cases the player will be either turtling, in which case they'll want you to keep throwing units at their defences, or just looking to practice new skills against an easy opponent.
