These guys will do ruinous damage to your air units no matter where you try to attack from, and since they are infantry the air units that are good against buildings are terrible against them. However, you can take control of this cannon yourself and use it against the Tau forces if you take control of the Critical Location point next to the cannon.ДЄlso, if you are playing a race that has air units that are good against buildings, unlike most other strongholds it is NOT recommended to use them to do quick raids to take out vital buildings not only is nearly every Tau base protected by at least a couple of Barracudas that are quite respectable at anti-air combat, every base has multiple entrenched Broadside Battlesuits spread throughout them especially the northwest main base.

It's not VERY strong, your main infantry will be able to survive a couple of hits, but this is still draining. Also, the Ark-Ka cannon emplacement is in the middle of the map and will periodically fire an anti-infantry blast at your forces, even if they are in the middle of your base. Destroying the first two will delay the reinforcements, destroying the final one will halt them entirely. The fleet is being guided by three beacons that are in bases on the eastern section of the map. There is also a count-down timer the Tau will receive heavy reinforcements from their fleet after a period of time. There are several bases scattered around the map with one big main one at the north west, and you have to destroy the Coalition Center at the middle of that north west base to win. Once you destroy all of the buildings there you will be given a primary Stronghold building and some builders, allowing you to finally start building up your forces. You have to move to the north, fighting as you go, to destroy a smaller Tau base and take over the area. You start out without a base in the south west section of the map, but with some additional forces along with your Honor Guard. Honestly this map can be a bit of a tougher one. The Tau then constructed a massive artillery emplacement as part of their conquest plan, called theВ Ar'Ka cannon, which could fire on any habitable territories in the system. Within days of their arrival, theВ Earth CasteВ had already created localized atmosphere, water supplies and a great plateau. Kaurava II's second moon was secretly settled by theВ Tau, who renamed it Nan YanoiВ (or 'sword-moon') and constructed a military complex on it.

It is located on Orridune, a moon orbiting Kaurava II. Nan Yanoi is the stronghold for the Tau Empire forces in Soulstorm's Single-player campaign. Such a feat would be be extraordinarily difficult, but it might just be possible. An invasion fleet could be shot down, but they could not as easily protect against a small force from making a beachhead at one of the gaps in the Tau's outer defenses.

Many systems and fortifications were not yet fully operational, including the perimeter defense system. Unfortunately, the Tau stronghold was attacked before it was complete. When complete, Nan Yanoi would be unassailable. To these they added an ambitious orbital perimeter defense system, which would fire ion beams, similar to that the Ar'ka Cannon, tuned to harm only intruders and spare Nan Yanoi's infrastructure from any damage. Heavy fortifications and anti-aircraft arrays were not enough for the Earth Caste architects of Nan Yanoi.

This weapon could fire it's devastating ion beam on any territory of any planet in the system. This moon base had been named Nan Yanoi, or ' Sword Moon ', referring to the powerful Ar'Ka Cannon built there. In a Tau-dominated solar system, this complex would become a key outpost on the Empire's border. The vast Tau military complex on Kaurava II's second moon had always been intended for purposes above and beyond the current war.
