Iron Wolf: Demons Within/Light in the Dark

In a wartorn city street, 2 guys are talking about whatever they've done was ethical. One guy, a black person, responds that whatever makes them get their paycheck, is ethical. The other one, a white person, challenges this view again, but they are interrupted by the sound of gunfire in the distance, followed by comms saying that another push is taking place. The 2 men run towards the source, with the white person mumbling "whatever gets me home", where they try to engage in a firefight.
They are quickly pinned down by the gunfire and the black person is hit in his shoulder and collapses, making sounds of agonizing pain. Upon trying to reach him, the white person is shot in his leg and falls against a car to dug for cover. Fighting against the pain, he feels like giving in to the temptation of sleep. His mind slowly drifts away, showing a vague imagery of a woman, which makes him snaps back to reality and he grabs a note from his vest. He looks at it and smiles in relief. It shows the note, saying "You are my hero" in scribbly lettres.
