Published examples vary sharply by manufacturer and launcher qualification: conventional HE rounds commonly list 13-16 kg class masses, product-specific explosive fillings, point-detonating or proximity fuzes, and range limits tied to barrel length, pressure limits, smoothbore qualification, or turreted-system requirements. In the Boko Haram insurgency, Nigerian Army reporting documented recovered 120 mm mortar bombs as insurgent materiel rather than confirmed firing use.

Product data frames it as an anti-personnel and anti-materiel round for shelters, fortifications, buildings, light armored vehicles, and automobiles, while open-source reporting places it with Boko Haram- and ISWAP-linked materiel in Nigeria and Ukrainian forces around Bakhmut.
