T-72 Gunnery

First person view. The armament system is fully stabilised and calculates elevation based on laser ranging but contains no lead computing. Moving sideways from the target or going down hill and firing even with a stabilised system will make the shell move at an equal speed sideways or vertically, making a hit beyond 1km range unlikely. Soviet non-export vehicles compensate for both vertical and horizontal movement with analog ballistic computers. More minor factors such as crosswinds and humidity are not calculated. Air temperature is set manually by a small dial. Unlike the T-64 or T-80, the gunner in the T-72 has to press a button every time a loading is desired. The loading takes about 6 seconds, it takes 7 seconds for the carousel to make a complete 355* turn, but due to regulations on ammo placing in the carousel, it ussually takes no more than 2 seconds to swing to another ammo lot. The loading and the whole gunnery procedure in this video is not edited in real time, but repeatedly from different angles, the whole loading, ranging and aiming ussually would not take more than 15 seconds. Effective gun range: 4000 meters with HE-Frag 2100 meters APFSDS [400mm @ 2000 meters] 1800 meters HEAT [550mm] 5000 meters 9K120 Svir [850mm] (only T-72B) Due to limits in dimensions, the stabilisation system of the T-72 is somewhat underpowered and can't cope with sudden direction changes such as vertical drops. The T-72 is a progressive tank. Earliest models used stadiometric ...
