Glow rods are used by United Nations Space Command personnel to aid aircraft during take-off and landing. Frontline troops are also known to utilize glow rods to designate areas for resupply of ammunition, armaments, and equipment in lieu of chemical light sticks.
A Marine uses glow rods to guide a taxing aircraft in Halo: Combat Evolved.
