Answer 1

"Many individuals demonstrate the heroic characteristics of loyalty, courage and leadership in the trying wartime climate."

"Rudi's self sacrifice for the children is the ultimate display of heroism."

Perhaps just "trying wartime climate" ?

Answer 2

1st Topic: The Machine Gunners

2nd Topic: Examples of Leadership, Heroism, courage in War
