Two element tank FIGURE 1 shows a low silhouette, articulated main battle tank 10 in the gross weight class of about 22 tons. Tank 10 is divided into a leading element 12 and a trailing element 14 so that its gross weight is distributed over a greater area, permitting the tank to operate over terrain, which would otherwise be marginal or impassable for conventional tanks. Leading element 12 serves in the same capacity as a conventional tank; that is, it carries the main armament, here represented by turret 16 and guns 18. Element 12 carries a complement of three crew members. The latter are represented in FIGURE 2 as the tank driver 20, shown in a supine position, a gunner-loader 22, and a tank commander 24.
Trailing element 14 is designed principally to carry tank support personnel, stores, and the tank power plant. The tank support personnel are represented in FIGURE 2 as crew members 26, 28, 30 and 32. Element 14 also carries secondary armament, here represented by an antipersonnel type gun 34 carried in turret 36 (FIGURE 1). Element 14 is also provided with hatch covers, represented by 38, 40, at the sides and rear of the crew compartment, which can be opened for additional support fire by the crew members. Element 14 is also provided with a door (not shown) at the rear of the element through which the crew members can dismount and attend to various tank support activities, such as clearing road blocks, removing mines, detecting and engaging enemy infantry, tank-killer teams, and establishing defensive positions should the tank be immobilized.
