Also known as: ギラ・ズール, AMS-129, AMS-129ギラ・ズール
A fictional Mecha from the Gundam series. It first appeared in Gundam Unicorn.
AMS-129 Geara Zulu
The successor to the Geara Doga MS - cheap, reliable and easy to produce and pilot, in line with its distant ancestor, the Zaku II. Its head has been redesigned and resembles a Stahlhelm with a gas mask shaped vent, and its improved beam machine gun seems heavily inspired by the StG 44.
While not cutting edge by any stretch of the imagination, it's still a serviceable, solid MS for Full Frontal's Sleeves - his personal brand of Neo Zeon.
