The Knight's Cross of the Iron Cross and its variants were the highest awards in the military of the Third Reich during World War II. The Knight's Cross of the Iron Cross was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry.
