"Shielding Grids are the most basic of Forerunner energy shielding systems, used primarily by Sentinel-class constructs despite having been considered outdated by Forerunner military forces before the Forerunner-Flood War. Shielding Grids utilise interlocking hardlight shield platelets, positioned so as to maximise force-resistance. Despite their obsolescence in comparison to general-issue Forerunner military protective systems, shielding grids have continued to remain largely superior to comparable Covenant and Human shielding systems; though shield strength tends to vary by unit, most shielding grids are capable of withstanding large volumes of fire by ballistic, plasma, and radiation based weaponry."@en . . .
