The RGM-79FP GM Striker is a ground close combat mobile suit and variation of the RGM-79C GM Type C. It was featured in the original design series Harmony of Gundam, the manga series Mobile Suit Gundam - Acguy: 2250 Miles Across North America, as well as the manga series Mobile Suit Gundam: We're Federation Hooligans!! and its sequel manga series Mobile Suit Gundam Katana.

From the data collected by the RX-78-2 Gundam and the RX-79［G］ Gundam Ground Type, the Earth Federation Forces recognized the frequent occurrence of close combat during mobile suit battles, as well as the effectiveness of the Principality of Zeon's close combat-specialized mobile suit, the MS-07B Gouf. It was decided that the RGM-79C GM Type C, one of the general performance improvement variants of the RGM-79 GM still in development, would serve as the basis of a specialized close combat GM variant.

The GM Striker was equipped with a set of full body additional armor known as Wearable Armor, based on the reactive armor used by the RGM-79F Desert GM as well as existing research on Chobam Armor, designed to protect the mobile suit from the ballistic weapons used by Zeon mobile suits. It was also fitted with a high-thrust backpack and improved leg thrusters. Weapons wise, it is equipped with one to two Beam Sabers, two Vulcan Guns, a 100mm Machine Gun, as well as an experimental Twin Beam Spear, a weapons with twice the firepower and reach of the beam saber. Finally, it has a Spike Shield, which can serve as a striking weapon in addition to defense.
