I want to max out Psi Operative's will , to that I need to get my shaken status, but despite getting him gravely wounded in my last battle, he did not get shaken. Is there any way to make sure he gets shaken ? I'm tired of walking into enemy fire and firing rockets on my own men.
Given that your soldier already has been shaken he can't be shaken again.
For reference look up the earlier question: What's the best way to prevent my squad members from being shaken?
