The British Mark I was a tracked vehicle developed by the British Army during the First World War, and the world's first combat tank. The Mark I entered service in August 1916, and was first used in action on the morning of 15 September 1916 during the Battle of Flers-Courcelette, of the Somme Offensive.[2] Born of the need to break the domination of trenches and machine guns over the battlefields of the Western Front, it was the first vehicle to be named "tank", as an expedient to maintain secrecy and to disguise its true purpose.[3] It was developed to be able to cross trenches, resist small-arms fire, travel over difficult terrain, carry supplies, and to capture fortified enemy positions. It is regarded as successful in many respects, but suffered from many problems owing to its primitive nature. en.wikipedia.org/wiki/Mark_I_tank

Richard Norton Thank you for your comments!

This is possibly an M-1917 tank which was a copy of the French FT-17 built by Renault.

Rino Deltombe Under the gun is a lifting hook. The M1917 had it but the FT17 did not :-)

There are more differents you can see. Like the front corners of the hull.

The Renault FT, frequently referred to in post-World War I literature as the "FT-17" or "FT17" (see Nomenclature), was a French light tank that was among the most revolutionary and influential tank designs in history. The FT was the first armored tracked vehicle or "tank" to have its armament within a fully rotating turret, The Renault FT's basic configuration - turret in the front, engine compartment in the back and protruding tracks (at least in front) - inaugurated the standard pattern repeated in most tanks to this day. Armour historian Steven Zaloga has called the Renault FT "the world's first modern tank". en.wikipedia.org/wiki/Renault_FT

This is the Ford 3 Ton Tank at Fort Knox, Ky. It has been moved to Fort Benning, Georgia. [http://www.flickr.com/photos/us_army_rolling_along/2848595115/]
