In Reach, there are 2 chests that are have valid entries, but are not included in the armory listing, These chests are UA/Base Security and UA/Multi-Threat. The chests are available with a grenade belt via Waypoint (UA/Base Security [W]) and Preorder DLC (UA/Multi-Threat [W]), respectively, but IMO that grenade belt looks tacky Edit: At some point, GPD injecting got patched. So the only way to obtain these is via JTAG or by following this image: (Search your Service Tag in Unicode) (Your screen will look nothing like this.) To make things easier, set all your armor to default except for your chest, which should be HP/Halo. DON'T FORGET TO RESIGN THE GPD WITH HALOSIGNER Pictures: inb4 copy and paste on other sites Enjoy!
