It’s June 6, 1944 – D-Day – and Canadian soldiers are under deadly fire as they disembark onto Juno Beach. The men are among the first wave of troops who’ve been tasked with seizing this stretch of French coastline from the Nazis. German opposition is stiff. But one thing that perhaps reassures the men is the fact that they’re wearing Mark III steel helmets – the latest in British-made protective headgear. And while each helmet won’t necessarily stop a direct hit, these vital pieces of personal armor can certainly deflect the lethal shrapnel that’s flying around.
