Walkthrough:Barrage the Boom Mines to take out as many of them as possible. Try to destroy one or two Machine Guns with the same Barrage as well, because you might need to take them down in order to succeed. Throw a flare onto one of the Flamethrowers, pre-smoke the beach, and deploy Troops. As the Warriors gather onto the Flamethrower you flared, throw another Smoke Screen onto the Flamethrower, then flare the Headquarters, and use the Smoke Screens as necessary to cover up your Warriors as they run towards the Headquarters. Once the Warriors have reached the Headquarters, shock as many Machine Guns as possible, and let the Warriors continue the attack from there on. They should be able to destroy the Headquarters in time before the Machine Guns start to react.
