Arado Ar 232 was a German World War 2 medium transport plane. It was the most advanced plane of its type and the first modern transport. Military transports still follow the principles set forth in this design, essentially a flying boxcar with high tail, rear ramp for loading and low clearance wheels. Only 25 were made but they were reliable and very well liked for their capabilities, including being able to move small vehicles and gasoline.

Many American GIs took a heart shield bible with them into combat, given to them by loved ones. Most consisted of the new testament, were covered with metal plates, and kept in a soldier's shirt pocket, over his heart. The intent, of course, being to stop an enemy's bullet from striking their heart. Link has photos of one with inscription and metal plate.
