Many soldiers suffer PTSD and can experience nightmares or anxiety because of it. some soldiers act cold when they return home or more distant than they once were. its common for soldiers to feel more on edge and lack being vulnerable.
They will probably feel a little stressed. I mean think about it most soldiers, when they come back from war, have PTSD. These soldiers are gone for long periods of time and the world changes day by day so they might not be used to how things work because all they know is war.
