The MS-06F Zaku II Real Grade is the same great kit as the Char's Version (linked below), but green.  Just like the Char's the Real Grade MS-06F Real Grade is assembled using a flexible inner frame which comes molded on a runner, and different shades of green armor.  On top of that, because this is the grunt suit you choose how you want your Zaku II identified, thanks to various stickers provided on the decal sheet.
