UNSC shield

The shield is a piece of UNSC equipment. At some point, an early prototype model was created based off research into the arm-mounted shields wielded by the Mgalekgolo.

Production notes
The shield is featured as the background shield found on the difficulty emblems for Easy, Normal, Heroic and Legendary difficulties in all currently-released Halo games. It is given some in-universe flavour text in the menus for Halo 2's PC port alongside the Machete. In the Bungie-era Halo games, the shield was emblazoned with the Marathon symbol, though following the transition to Halo 4 and 343 Industries, the shield now features the Reclaimer symbol.
