"Iron Youth"

 In Kantorek's letter to the young men, he calls them the "Iron Youth," implying that they are hard, strong, and resilient; a description that fails to take into account the horror of the war, trapping the men in a constant state of panic and despair.

The average age for enlisted men was 25,  but soldiers as young as 14 or 15 also served.
