Attacking and defending is, in most peoples opinions, the most fun part of the game. By building up a military, you can send out troops to another empire in an attempt to destroy them. If you win the battle, you will get a portion of their resources! With a large enough military, you can also defend your empire, to attempt to stop other players from stealing your resources.

When an empire is first created, it does not have attacking and defending capabilities. Your empire will not have these capabilities until military advances have been made. To start off, you need to research Armed Forces. Armed Forces costs 125 knowledge to be researched. If you do not know how to research something, you must first build a school, then put workers into learning, and finally save up enough knowledge points for the item that you want to research.

By building up a large military force of land units, tanks, and/or planes, you can send out an attack to other empires. Each time you do this, it take one mother-ship from your empire. Since you have a maximum of five mother-ships, you may only have 5 active attacks at a time.

There are many upgrades for your troops which you can get only by researching, and the difference is noticeable. Getting the corresponding armor and weapon upgrades for your troops is highly recommended.

Additionally, there is a Universal Law in place that prevents you from attacking anybody who's empire has less than 50% of your worth. This ensures fairness and stops low-worth players from being driven into the ground. If the round is in Chaos mode, there is no 50% law!

Sending an attack is fun and easy! In order to attack another empire you need to click on General Five Stars, or click on "Military" from the options bar, then select the attack link and enter your victim's Round ID in the input box. Once you have done that; all you need to do is select the types and numbers of troops you want to attack with, send them off, and then sit back and wait for the results.

If the attack is successful, you can steal the enemies resources! The minimum amount is 10% while the maximum amount is 70%. If they have a Empire Protection, you will gain less resources. In a combined attack with a maximum of six other alliance members (total of seven including yourself) the loots will be equally shared among all the attackers. Scroll down to Combined Attacks section for more information. Here's a more in-depth explaination about Attack Reports and Defense Reports.

The attacks can be stopped by the enemy empire from their defense and/or spycraft! Blue-Ops have the capability of infiltrating your empire and destroying you Command Center! If the Commander Center is destroyed, ALL your attacks will be stopped! There is a better explanation of Blue-Ops and other Spycraft units in the Spycraft Page.

Be careful! While your troops are away, somebody may launch an attack on you! You should always try to keep some troops at home in case this happens, or you could wind up losing a lot of resources. The minimum resources stolen is 10% while the maximum is 70%! If you have Empire Protection on, you will have less resources stolen. Empire Protection increases when you get attacked multiple of times.

There are other ways to stop attacks too, and you'll need to look out for these when you're attacking other empires as well. Defensive structures are buildings that come in many degrees of power and cost and they help defend your empire when it is attacked. Once they are unlocked, you can build them by clicking Bruce/Construct.

Note: Defensive structures can be destroyed in battle, just like troops. When a defensive structure is destroyed, the land used in building those structure is not given back. I.E. You have 500 free land out of 1000 total land, then you build 100 land worth of bunkers. Someone attacks you and you lose all of your bunkers, you will not have 500 free land again but you will have 400 free land as if you still obtained the structure.

A new feature added into UWars in a more recent round is called Combined Attacks. This Feature allows you to pool your military with six other alliance members and send it all at one target, in one attack. This makes it easy for even relatively low-worth players to take down a high-worth player.

1 The first is to go to the Attack option on the Military page, type in the victim's Uwars ID, and look for the drop down menu (1) that lists attacks in progress. You will need to select the name of the empire that launched the attack you want to join. There is also an option that allows you to prevent members of your alliance from joining your attack. It can be found at the drop down menu at the bottom of the attack preparation page (2).		2 The second is to detect alliance attacks in the Attack option of the Military page. From there, you can enter the target's ID and join the attack through the first method.

Another new feature added into Uwars in Round 2 is defending alliance members. When another empire might be launching an attack on an alliance member, you can send troops to defend them. You cannot defend people 50% below your current worth. But be warned, your troops stay away for 12 ticks and leave you open for attacks as you can not cancel this option! With that being said, its not wise to send your whole army to defend.

With the new updates in Round 10, there is a restriction on the amount of defenders! Only six other alliance members can defend an empire

At first, when you build your Command Center, you will only be able to attack people on your planet. If you buy a Launch pad you will be able to attack anyone inside your galaxy (launchpad available in the second age after you have built your space center). To attack people outside of your galaxy you will need to wait until the 3rd age and build a space station (not to be confused with space center or space port)
