What does GRD mean?

Hello Halo Community,

I, like many other fans, have been trying to figure out what GRD means. This is part of the morse code signal heard over the radio(s) featured in the Halo: Infinite Trailer. I have been doing some research and have come up with the following acronyms for GRD:

Genealogical Research Directory
Grease Recovery Device
Government Research Directory
Global Research and Development
Government Relations Division
Geologic Resources Division
Geosciences Research Division
Global Resource Director
Geminiviral-related DNA
Geminivirus-related DNA
Geograpic Reference Database
Geological Research Division
Genesis Race Division
Gamma Ray Detector
Genetic Reconfiguration of DSPs
Geological Resources Division
Government Relations Director
Geopysics Research Directorate
Global Relief Data
Gross Residual Disease*
Ground Residual Distance
Gateway Routing Daemon
Global Research and Discovery

I think Gross Residual Disease stands out. Residual disease might refer to the Flood, which, coincidentally, also existed on Zeta Halo (a.k.a. Installation 07). Interesting?

I welcome discussions regarding GRD and it’s meaning. Did I miss any possible definitions? Please comment below. Thanks!

Where exactly did you see this ‘GRD’? in the trailer? If so, where?

Maybe it’s related to the helmet.

it was in the translation of the code which is SOS ZETA HALO GRD
