The weapon consisted of an unrifled tube with a crude breach mounted on a Y shaped pedestal which pivoted on trunnions to provide elevation.
 Two breech mounted inverted horns were provided for traverse/elevation and a simple inclinometer for targeting and range calculation.
 A black powder charge was inserted into the breech and fired by a percussion cap to propel the AZh-2 glass ampule.
 The ampules were filled with an incendiary mixture known as KS.
 KS was a mixture of 80% phosphorus and 20% sulfur which ignited when exposed to air.
 The burning mixture created a bright flame, thick white smoke and would burn for up to three minutes at temperatures between 800–1,000 °C (1,470–1,830 °F).
 The burning liquid would seep through vision slots or engine grilles on a tank and ignite ammunition or fuel as well as choke and blind the crew.
