1:72 Scale Metal Die-Cast ? Chieftain British - UK Main Battle Tank - Length: 5.75" (from end of vehicle to tip of the main gun) Width: 2? This Chieftain tank model's upper body is made of metal while everything else is made of plastic. The tracks are made of rubber and are fitted, however they do not move. The coloring and markings are accurate and realistic. The maker of the model really did a good job with, the panel lines and details are very clear and crisp. These models have different details engraved such as doors, hatches, panels, lights, ports, antennas, machine guns, ropes, shovels, etc; all of these done with high accuracy and proportion. When they are painted in different color, say for example, shovels and ropes, they are indeed painted accurately. Depending on the particular type of tank, some will have machine guns and antennas that look very accurate These models come in really nice packaging. The model itself is attached (via screws) to a plastic base which is made to look as rough terrain. The base measures about 7 inches by 3 and at one side of the base is some info about the model such as the type of tank, the outfit it belongs and the time period it served. Moreover, the whole base can be topped with a transparent acrylic top which encases the whole tank in a rectangle that measures roughly 7 inches by 3 inches by 3 inches high. Lastly, each model comes in a very basic disposable blister pack. These models are not toys, they will not last long if played with. The tracks don't move and the turrets and their main guns and machine guns can be quite fragile because of their size. Some of the tanks will have a turret that does not rotate at all. (so if you try to rotate the turret or change the elevation of the gun and feel some resistant, better leave it alone and don't risk breaking something). The FV4201 Chieftain was the main battle tank of the United Kingdom during the 1960s, 1970s and 1980s. A development of the Centurion, the Chieftain introduced the supine (reclining) driver position to British design enabling a heavily sloped hull with reduced height. A new powerpack and improved transmission gave it higher speed than the Centurion despite being heavier due to major upgrades to armour protection and the armament: this allowed it to replace both the Conqueror and Centurion while performing their roles effectively. It remained in service until replaced by the Challenger 1 which shared a large number of the Chieftain's features.
