This is a sectional view of a cruiser tank. The vehicle is driven by a high horse-power engine K, through a clutch L and gearbox to a rear axle M. This axle drives two outside sprocket wheels O. which in turn drive the caterpillars. The shock-absorbing mechanism P. enables the tank to move at high speeds over very rough ground. This mechanism is shielded by armour at Q. Direction Is controlled by two levers F and J (see also photo below) which act as a brake on the caterpillar on the Inside of the turn, while gear is changed by the lever H. The driver G looks forward through two small slits. The gun-turret A revolves mechanically and the three-pounder gun B is laid by gunner D and loaded by E. There are two half-inch Vickers guns at C and N; a third is on the other side of the tank corresponding with N. The mechanisation of the British army has led to the establishment of the Royal Armoured Corps, in which are included the Royal Tank Regiment and all the Cavalry and Yeomanry regiments that have been mechanised. The tanks of the Cavalry and Yeomanry are of the lighter type, successors of the "whippet tanks" of the last war. These machines are manned by three men, and are not only faster but much easier to handle than those that went into action in 1918. The heavier tanks, sometimes known as "cruisers." are used in conjunction with infantry, preceding an advance not only to machineÃ‚Â¬gun the enemy but to clear a way through barbed wire entanglements and other obstacles. The future crews for tanks, of all types were trained at a special school, a scene in which is shown in this thread. The course of instruction the men undergo includes driving, for every man of the crew must be able to drive, and also a thorough technical knowledge of the working of the very complicated piece of mechanism of which they are to have charge.
