that Gundam seems to be more like a variation of the Origin version of Amuro's RX-78-2, especially because of that shoulder canon design which is usually seen in Origin-related contents. Basically another new Gundam type MS introduced for the One Year War, although this show might be like the Origin in that it's not canon. This does gives MS IGLOO vibe, so it would be like MS IGLOO 3 (since there is IGLOO 2 serkes which tells stories of EF soldiers)
