The current system (anything is open to change if it turns out too many ways to exploit it are found in beta):
You bring 10 troopers.
You build another 20 troopers.
You now have 30 troopers.
You lose 15 troopers.
You end the fight with 15 troopers.
Trooper survival rate of 50%.
Oh, I'm sorry - I was going on assumptions about the system. My bad.
