The Huckebein Mk-III Type-L (ヒュッケバインMk-III・タイプL) is a Banpresto Original Mecha debuting in Super Robot Wars Alpha. Part of the Huckebein Series, it was developed from the Huckebein Mk-II, with its brother unit being the Huckebein Mk-III Type-R. It can combine with the AM Boxer to form Huckebein Boxer or with the AM Gunner to form Huckebein Gunner.

The Huckebein Mk-III was developed by Mao Industries as the successor of the Huckebein Mk-II, based around the concept of "a miniaturized high-performance SRX". Also known as a "Super Personal Trooper", it is equipped with a T-Link System and Uranus System similar to its predecessor, an improved Gravi-Con System allowing for better usage of Gravity Territory, as well as a new Tronium Engine. For the Mk-III, output regulation of the Tronium Engine isn't manually adjusted like the SRX but through the pilot interacting with the T-Link System instead. It adopts the Huckebein's H Frame and the Huckebein Mk-II's Personal Fighter module system, along with using various parts from the R-Series mecha. However, the Mk-III's most distinctive ability lies in the Core Trooper System, allowing the Mk-III to equip either the AM Boxer or the AM Gunner support modules to form either the melee-based Huckebein Boxer or the artillery-based Huckebein Gunner respectively, granting the mecha the ability to respond to various combat situations.
