Two choices, I took top. Build the refinery, barracks, light factory, and upgrade everything you can. Scout extensively to build an "area of watching" - there's no 'Fog of War' here. Put a strong set of troops around your base. Then put together a pack of at least 5 trikes and head out to their base (right side) to attack them. Again, not too tricky as long as you leave some guys behind to hold down the fort. The enemy has a tendency to "ride the air carrier" in to right next to your base. A shame you can't do the same ...
