The last major German offensive campaign on the Western Front has become known as the "Battle of the Bulge" for the thrust into the Allied lines. For the Americans, this was to be the largest and bloodiest single engagement of the Second World War, and also the third deadliest campaign in American history. It began 75 years ago on Dec. 16, 1944, and while it caught the Allied forces off guard, in the end, the German Army failed to meet its objectives and the battle essentially exhausted the Germans of their resources.        

Along with bravery and determination, it took innovation and ingenuity to capture, secure and hold the Normandy beaches on D-Day. Technology played a key role. While not every innovation worked as planned, used together these all helped ensure victory in Operation Overlord.

When Allied forces landed on the Normandy coast on D-Day their success hinged on several technological innovations.

Deception played a big part in the Allied invasion of Normandy on June 6, 1944. From dummy tanks and landing craft to the creation of a “ghost army,” these are some of the remarkable tactics that fooled the enemy on D-Day.

It was 75 years ago that the Allied forces undertook Operation Overlord, the codename for the invasion for the Battle of Normandy, which involved the D-Day landings that were actually codenamed Operation Neptune.

Bicycles may not be standard military hardware, but they have been used by a number of armies since the late 19th century.

In many parts of the world the bicycle is the main means of transportation as people commute to work. Cycling, for many people, is a way of life, but it also has deep roots in military history throughout the world.

The phrase "an army marches on its stomach" has been attributed to both the Emperor Napoleon and Prussia's Frederick the Great – but regardless of who said it, many soldiers in the field would argue the importance of effective military boots.

From tall leather boots to modern military footwear, these images show the evolution of combat boots.

From the Browning Automatic Rifle to the M16 and the new upgraded M4A1, America’s combat rifles have undergone a dramatic transformation over the last 100 years.
