So im on the second mission and im about to complete it and i come across an event where i can help out some comrades. I send in my nurse unit who has a 70% chance of success... What happens is i rescue my comrades but get my nurse killed. There is no spending resources to keep the unit or any warning that the unit could get killed etc. No save game or ability to purchase another nurse unit. I dont think this is fun and i dont want to keep replaying games over and over and have almost no control of units killed. Annoying!
