Yeah, that's a basic defect in the way this (and similar) games are set up; it's hard for you to replace any casualties (limbs, pawns, etc.) but the people attacking you have an endless supply of suicidal maniacs. If you're taking any significant casualties in a battle you're going to be ground down to nothing pretty quickly.
This is one of the things that makes turrets so great. Go ahead, blow them up, it's easy to make more!
We need some other resource that can be consumed by battle which takes time and effort to replace but not too much. Ammo, for example... "oh crap, yeah, all my pawns survived the battle, but I'm out of 0.50 sniper ammo, gotta start making more at the reloading bench!"
Maybe if we had alien attack chickens that only took 5 days to hatch and 10 to reach adulthood?
