Embrasure

The frontal wall of the pillbox has the antisplinter armor covering. The chill cast iron embrasure casting turn the scale at one half ton. The semiautomatic 45-mm antitank artillery system with duplex 7.62 machine-gun was mounted on the pins of the embrasure. The toothing guide for horizontal moving of the gun is seen on the picture. The sector of fire was 45°.
