Tank crew notebook Ecopybook T64 A6

The T-64 T64 A6 Tank Crew Notebook by Ecopybook is a unique tool developed and produced at the initiative of the Center for Combat Equipment and Management of the Armed Forces of Ukraine (CMBMU) based on the "Firing Table for the OF-26 High Explosive Projectile for the 125 mm D-81 Tank Howitzer". These firing tables were approved at a meeting of the methodological commission of the Central Course of the Railway Military Unit B0934 by Protocol No. 1 of January 06, 2017.
The notebook consists of reference material that contains important information on the impact of firing conditions on the flight of a projectile and their accounting, tasks performed by tank units firing from closed firing positions (CFPs), firing positions, and the abbreviated preparation of initial data from a map (firing board) without introducing corrections, correction of the direction of fire when a projectile deviates by 50 meters, rectangular coordinates, determination of rectangular coordinates using an AK-3(4) and an officer's ruler, marking points on the map at the specified rectangular coordinates, fragmentation and high-explosive effect of projectiles, the procedure for installing a fuze, a T-64 tank lubrication map, and a tank fire map.
This notebook is an integral assistant to the T-64 tank crew, providing the necessary information and instructions for effective firing and fire control. It helps to ensure accuracy, coordination and safety during combat operations, ensuring the successful completion of tasks in demanding combat conditions.
