Armored Infantry Ground Units

Armored Infantry Ground Units (AIGU's) are a form of mechanical infantry armor, first manufactured by Animus Global Corporation in a classified government project that took place around 2005-2015. Not much is known about them, but it is known that Quill T. Wolf mentioned in a speech that he would decommission the program along with several others to further focus on the commercial space travel industry.

History
Around the beginning of fall of 2005, Sparky Wolf took it upon himself to further fund the X-1 program, going so far as to secretly initiate the AIGU program. The US government saw this as an opportunity, and immediately gave Animus funds to manufacture and ship over a thousand AIGU's to the government for the Army, offering about 15 million dollars for their cooperation. Sparky immediately took this opportunity and began designing and manufacturing the AIGU Mk.1 (Minerva) right away. After this period in time, not much is known about where the program went, but it is known that it was used at some point, as demonstrated Interview Log #54-A. However, it is known that multiple versions were made, the latest being the AIGU Mk. 3-b.

Use by the Animus Imperial Army (Animus Universe)
Directly after Sparky took over the US, he employed several AIGU units across the world to suppress resistance before he bombed capitals and major cities of said countries. They were also used by the Animus Imperial Army in The Sword War to suppress the resistance before they attempted to take over the land.

Use by the Nebula (Myriad Universe)
Some AIGU's are in service for major Nebula leaders, such as Quill, Dante, Swindle, and a few others.

Use in the Apocalypse (Post-Apoc RP)
Various factions throughout the Acropolis wasteland own at least one AIGU, with an exception being the Dragons and Drifters.

Trivia
It is rumored that the design for the AIGU Mk. 2a is based off of the T-51 from the Fallout Universe.
