Integrated Helmet and Display Sight System

The Integrated Helmet and Display Sight System (IHADSS) is a computer system used by the designated gunner on D77 Pelican dropships (and presumably those of UH-144 Falcons ). It determines where the gunner's eyes are focused and aims the M370 autocannons accordingly.
