The shooting training had one gap in the squadron: namely, the squadron had no special aiming instruments.
While in the British unit some of our men and officers became acquainted with these instruments, a graduated sight and a protractor. In addition, there were two rangefinders per platoon and sliders for calculating angles1 (like shooting tables). The squadron received rangefinders, sliders as well, but it did not receive rangefinders and protractors, as a result of which it was impossible to fire from concealment (probably using old Polish methods).
As mentioned above, the squadron had all the equipment, i.e. 25 carniers, but the old carniers had no adjustments for CKM. The rifle was carried normally like any other equipment on a carnier. The CKM could not be fired from the carnier, but had to be resisted. It was not until the first half of February that 12 carriages were exchanged for brand new ones with adapters, i.e. with scopes on which a CKM was mounted, which made it possible to shoot from a carrier (also in motion). It was possible to fire in all directions, irrespective of the direction in which the vehicle was moving. The firing was done by the whole crew, depending on the position of the vehicle in the direction to the target.
