一、瞄具由于新型坦克增加了特殊装甲,炮塔的前方部位突出于炮塔转盘外,结果遮蔽了驾驶员舱口区域。在密闭的条件下驾驶,观察能力受到了限制,驾驶变得很困难,特别是遇到暴风雨天气。M1和豹Ⅱ坦克在安装观察装置的空间受到极大限制的条件下,才能给驾驶人员以广阔视野。这两种型号的坦克都使用了三具驾驶用观察装置。这三具观察装置在豹Ⅱ上是这样安装的:中央和右边的观察装置安装在驾驶员舱口上,左边的观察装置安装在驾驶员舱口的外侧。这种安装布局能给驾驶员以140°的广阔视野。中央的观察装置能与夜视用的PERD53装置互换,密闭驾驶时,驾驶员的眼睛可以很容易地接近它。其他二具观察装置与驾驶员的眼睛是离开的。假如驾驶员想详细地观察左右情况时,可以调转头来观察。M1的三具观
First, the sights As a result of the new tank increased special armor, the turret turrets in front of prominent parts turret, the result of shielding the driver hatch area. Driving in confined conditions limits the ability to observe and makes driving difficult, especially in stormy conditions. M1 and Leopard Ⅱ tanks in the installation of observation devices under the conditions of great restrictions on the driver to give a wide field of vision. Both types of tanks use three observation devices for driving. The three observation devices are mounted on the Leopard II with the central and right observers mounted on the driver’s hatch and the left observer mounted on the outside of the driver’s hatch. This installation layout gives the driver a wide field of view of 140 °. The central viewing device can be interchanged with the PERD53 device used for night vision, and the driver’s eyes can be easily accessed when driving in closed position. The other two observation devices and the driver’s eyes are left. If the driver wants to observe in detail about the situation, you can turn around to observe. M1’s three concept
