The GLA have infiltrated Hong Kong and have taken over the Convention Center. Destroy this structure and the two attached garages to complete the mission.
Yes, you probably feel pretty annoyed when your taskforce is destroyed by a GLA mine, but don't worry, the mission is far from being over. At the start of the mission, you have two Dozers, a Battlemaster and several infantry and rocket soldiers. To start:
A cut scene shows the train arriving delivering fresh Red Army troops for your command.
You won’t have to worry about base defense, so just focus about slowly carrying out your offensive mission. Take a combination of six battlemaster and gattling tanks slowly along the ocean-front street north toward the Toxin Tractor Facility. Park your vehicles near the intersection which leads to the Convention Center and let units build veterancy while GLA units unsuccessfully rush your units.
When the assault slows, head north toward the toxic facilities and destroy or capture them. Be careful of the spilt anthrax, as this will destroy both infantry and tanks.
Keep a close eye out for enemy units behind you while you are destroying this base, as your distracted troops can be destroyed while firing at the buildings, and remember to destroy the barracks on the far side of the toxic facility.
Go back to the base to repair your vehicles. Instead of heading along the obvious route to the center, take a soldier and send him down near the docks. Your forces are then greeted by a Ferry driver who will take your forces to the center. Load up a force of two Battlemasters and maybe a troop crawler or a Dozer and hit 'Transport.' Your force is then sent to the center. Because the GLA have no idea that you are in the the ferry so they will not attack it. Immediately send out your two tanks followed by your other vehicles or infantry.
Destroy the convention center and the two attached garage structures at the front of it to win the mission.
