When “doughboys” – a term of endearment U.S. troops embraced – stepped upon the European battlefields of WWI, they donned M1917 helmets.
Virtually identical to the original Mark I British helmet, the steel M1917 was first worn by the American Expeditionary Front on the war’s Western Front. The American version managed to advance the ballistic protection compared to that of its English counterpart.
The seeds of that war – famously christened “the war to end all wars” – were planted on this day 105 years ago when a German U-boat near the southern coast of Ireland fired a torpedo and sank the RMS Lusitania.
