It is designed for carrying out exercising and training fire without basic
ammunition expense equipped with the main systems with calibre of 125mm. The
inserted gun is located in the loading breech and breech ring of the main
system.
Firing is analogous to firing with the main system. Electric trigger of the
inserted gun is supplied from on-board main of the fighting vehicle directly
or from the block of loading simulator.
This very cartridge provides the full coincidence of the bullet trajectory
with the main shot trajectory, that helps to fulfil the training tasks more
economic and effectively.
