Invasion
Whenever a player has a fleet in the orbit of an enemy planet, and if that fleet contains at least 1 invasion ship and soldiers, he may invade the enemy planet. An Army Barracks is required to begin Training Soldiers
If there is an enemy fleet, you encounter a space combat before being able to invade. The invasion ship has very poor armour and fleet drive, and with all the expensive soldiers in the fleet it's very important that you provide enough Military Ships cover for this ship.
The invasion ship can carry 40,000 
Soldiers. Invading a planet uses all invasion ships in the invading fleet and all soldiers. The workers (idle+busy) and soldiers on the surface of the planet automatically defend against invasions.
The attacker will need 1 soldier for every 15 hostile workers to kill and 3 soldiers for every 2 defending soldiers.
The invasion is successful if the attacker kills every soldiers and workers in the planet. Then, the attacker takes control of the planet and the resources stored on it.
If the invasion fails the defender loses soldiers and defending workers depending of the number of invading soldiers, and keeps control of the planet. The attacker loses all soldiers and invasion ships that attacked. Workers are killed only after the enemy successfully killed all defending soldiers.
