Always try to have enough defense at home to avoid being attacked. That means either 50-70% of your military or more, or so much military that you would not want to attack yourself if you had been your own opponent.

Star Kingdoms is a war game. You can survive without attacking others, but you will probably never do good at SK if you don't. Below are descriptions of the different military units. Some of them can only be used for offense, some of them only for defending your kingdom, and a few for both purposes.
Soldiers are drafted from your population (you can draft a maximum of 10% of your civilians every day into soldiers), and from the soldiers, you can train more advanced military units - Troopers, Dragoons, Laser Troopers, Laser Dragoons and Tanks. Tactical Fighters do not need any soldiers in order to be trained.
For most planet types, some of the military units have to be researched before they can be trained.

For every % of your land used for training camps, to a maximum of 10% of your land, military will be 3% cheaper, so a person with 10% training camps will be able to train a tank for 1225 money.

A kingdom's defense land is calculated with ((1x Soldiers + 4x Laser Troopers + 5x Laser Dragoons +9x Tanks) / your amount of land) * bonuses. The minimum defense for a kingdom is always 2x his amount of land defense points, and you don't get any bonuses to land defense, which means that a 500 land kingdom with 100 soldiers for defense will have 500 * 2 = 1,000 defense points worth of defense.
If the military defense is higher than the land defense (which it is in most cases), you don't need to include the land defense in your calculations.

• Tactical Fighters can only be used and constructed as long as you have air support bays. Every air support bay holds 35 Tactical Fighters, and that number is not increased by any bonuses or researches. So a person with 1,000 air bays can have a maximum of 35,000 Tactical Fighters sent out as most, even if he has more than that which are unsupported. If he gets attacked, it is only checked how many TF's which are in and supported, not how many of the supported ones which are already out.

•You have four different war leaders (WL's) to use when attacking. For each one extra you use, after the first one, you get a 3% bonus to offense. Your army will also return much faster if you use many war leaders. For example, if you send 10k tanks with one WL to attack someone which is 16 hours away, your 10k tanks will all return after 16 hours. With two WL´s used, 6k tanks will return after 8 hours, and the other 6k after 16 hours. With three WL´s, the return times will be 5-10-16, and with four war leaders 4-8-12-16.

DPA Calculator
Do you think your kingdom has enough defense/land? Or do you want to find out which one of several different targets which you gain the most land for the least losses when attacking? Enter the different stats in the calculator below, and you will get a DPA value. This value can be compared to the DPA value of friends, or other people which you've taken stats of (for example targets). If you don't understand how to use it, just click on "Help".
