RTB-7MA RPG round

The RTB-7MA is a Bulgarian thermobaric round for RPG-7-family launchers, pairing a 40 mm rocket motor with a 106 mm GTB-7MA warhead intended for personnel, field shelters, fortifications, buildings, light armored vehicles, and automobiles. In the Boko Haram Insurgency, open-source reporting places the round among Boko Haram and ISWAP-linked materiel rather than a regular state inventory item.
