A Sunburst Bombardment is a Tau military tactic that can be performed by orbiting Tau starships to aid friendly ground forces engaged in a difficult combat against a world's defenders. Sunburst Bombardments are often used to aid large-scale planetary assaults during the initial planetstrike. When the command is given, the skies over the target world flash with blinding white as the Tau launch a massive onslaught of Lumina Flares at the foe, saturating and confusing any automated defensive Auspexes or tracking stations with the light. The shadow-haunted battlefield is illuminated starkly, each enemy stronghold now a glimmering beacon for the Tau forces' concentrated fire.
