Milkor MGL (ダネル MGL Daneru MGL?) is a six-shot semi-automatic grenade launcher featured in the ALDNOAH.ZERO television series. The MGL is a real-life grenade launcher manufactured by the Milkor corporation of South Africa, and is currently used by a dozen militaries including the US Marine Corps.
The weapon is presumably used by the United Forces of Earth, being found inside of the Kataphrakt transport vehicle, and is one of the weapons used to launch smoke grenades around the Nilokeras, blinding its aerial cameras. The weapon is fired by Princess Asseylum Vers Allusia, while being disguised as "Seylum". (AZ: "The Children's Echelon")
