Anno 2070 involves Combat at sea (with Ships), in the air (with Aircraft) and underwater (with Submarines). Aircraft and Submarines are new units to the Anno series, and therefore new tactics will need to be used.
There are many combat Soundtracks, like Civilian Casualties.
Also see Defences (strategies for defending a city).
|City management||A formidable navy relies heavily on good production chains/management and great skill in raising your population classes quickly.|
|Focus fire||Target one enemy at a time, rather then spreading the damage out. The enemy will drop one by one, resulting in fewer guns firing back at you.|
|Fleet choice||If your opponent focuses on aircraft or submarines build Commando Ships / Hovercrafts or Vipers respectively.|
|Attacking a town||Focus on turrets first, then Shipyards, and then keep his Fisheries down to starve his population of food.
To help prevent an attack on your town:
|Targeting Energy Production||
When attacking an island, attempt to destroy the most productive energy generating buildings (i.e. dams, solar towers). Going after small energy production buildings such as wind mills is inefficient and doesn't deprive the opponent of major amounts of energy. Turrets and Flaks rely on energy, and they will cease to attack if deprived of energy. This translates to the enemy losing a large part of their defenses, giving you a major combat advantage.
Warning: If you are fighting against computer players which have Nuclear Power Plants, do NOT destroy the plant because it will turn into a Nuclear Ruin, so it will make it impossible to defeat that player.
|Siege / Blockade||The point of enforcing a siege or blockade is to prevent materials from reaching an island without having to engage the island’s defenses. Most blockades will be the most effective when enforced on the opponent’s main island, or wherever is main city is. During a blockade, destroy all trade vehicles going to and from the island. This will deprive that island of goods the opponent is transporting it, and in the case of a city, necessary goods the population requires. If the blockade is enforced long enough, the population will begin to leave. The opponent will likely react in the following ways:
The blockade is an offensive tactic, and you will need to be able to build military ships quickly and have success with destroying the opponent’s ships or else you will be wasting time, money, and resources.
See also Island Shares and Hostile Takeovers.
A hostile takeover constitutes buying shares in an island until you are able to outright buy the island. You will not be able to purchase shares until you reach the third tier of civilization. Once you purchase a share, you will not be able to purchase another for 10 minutes. When you own 60% or more of the shares in an island, you can purchase the island. To purchase shares, click on the island’s Warehouse/Port Authority. A window will appear in the top right of the screen where you can buy the shares. You start with three purchased shares on your first Warehouse.
Preventing a hostile takeover:
|Commando Rush||Build many Commando Ships and attack your target in guerrilla-style.|
|Fleet Ordering||With 2-3 Ark NPCs on the map, bring your fleet limit to 1 below the maximum and lobby to increase influence. Then order a large fleet from any NPC, send them into battle on a pointless suicide misson, then, when you are under your fleet limit again, order another large fleet. Order from all NPCS; this works best when fighting enemies wth huge navies. Make sure to have managers and a good economy, as a large fleet costs $45,000.|

For an overview of these items, see Vehicle Items.
There are some items in the game that can improve a ship's stats (damage, health, movement speed). You can acquire these items from trading with an NPC, sending a ship on an expedition outside of the sector with the use of an item, doing missions for an NPC, or researching them at an Academy or Laboratory. These items (usually) use percentages for their stat boosting capabilities. Some items may only be fit to a specific class of vehicle (Warships vs Cargo Freighters), while some items may be fit to any vehicle of its type (any ship or any aircraft). Ships have only a certain number of Special Slots on which any kind of item compatible with that ship type can be fitted. Two or more of the same item may be used without penalty, provided the vehicle in question has more than one fitting slot.
Commando Ship Mayhem
You can build commando ships without having to produce any munition. You can do so by first purchasing a commando ship, and than quickly move the Ark to a new location. This will result in the commando ship becoming locked inside the Ark, and you will be offered a new Commando Ship by E.V.E, you can repeat this process as much as you desire, but do note that the more ships you purchase, the faster you must be in order to be able to buy more. You can build a fairly strong navy using this without the need of any munition, but do however note, that you must destroy all your commando ships before you can do this again, and it requirs 3000credits per ship, so build up cash before doing this if you decide to use this exploit.
Do NOT destroy any nuclear powerplants belonging to a NPC your fighting against. Because if the powerplant turns into a ruin, it will make it impossible to defeat the NPC. Its unknown what causes this, but it can be annoying especially in longer missions like the Power Game mission if you accidentally destroys a NPCs powerplant. You can avoid this by destroying the depots and/or warehouses supporting the powerplant which will cause it to collapse. The Deep Ocean expansion adds the Clearance Device Warehouse Item, which removes all ecobalance altering buildings, including Nucelar power plant ruins, but this option is not available in the base game, including Power Games.
