Atreides Only First off, build 6 snipers, If there are barrels around the builds of the base and such..thats all you'll need. If not, add 6 Mongooses and and 8 Bikes to the list. That should do fair, add stronger units as the diff. goes up. This should work when there are two entrances, bring the snipers around rear, and start picking off Infantry{ Or barrels }. All their units should come after the snipers then fly the bikes into the middle of the base to take out defences and the units from behind. Then have the Mongooses paste the base.
