Troops take out troops
The amount of attacking troops lost is between 0.25 and 1.5 multiplied by the amount defending troops (by default).[1] If there are plenty of defending troops, all attacking troops will always be lost. If not all attacking troops are lost in an attack, they return to the ship.
- Example 1: 500 troops attack a planet with 2000 troops. Since 500 (2000×0.25) is the minimum amount of attacking troops that can be lost, all attacking troops will always be lost.
- Example 2: 500 troops attack a planet with 1000 troops. The amount of attacking troops that can be lost is calculated as between 250 (1000×0.25) and 1500 (1000×1.5), but of course there were only 500 attacking troops. Therefore, there is a 80% chance all 500 troops will be lost, and a 20% chance that it will be between 250 and 500.
- Example 3: 500 troops attack a planet with 250 troops. The amount of attacking troops that can be lost is calculated as between 62 (250×0.25, rounded down) and 375 (250×1.5). Some troops will always return.
If the amount of attacking troops is less than 2% of the amount of the defending troops, the attack is unsuccessful and no defending troops will be eliminated.[2][3]

YAAAA!
Alternate scenarios
If you attack with troops while fighters are still present on the planet, the fighters will take out anywhere between 9 and 43 troops per fighter, before the troop-on-troop battle begins.[4] Troops cannot take out fighters.
Spies
Spies level of confidence is random number between 50 and 98.[5] For example, if the spy has a level of confidence of 75, the amount of an item reported can be anywhere between 75% of the actual amount and 125% of the actual amount.[6]
