Operation: LEFT JAB was an operation of the United Nations Space Command during the Fall of Reach in the Epsilon Eridani system on August 14, 2552. Desperate to destroy the Covenant Sh'wada-pattern supercarrier Long Night of Solace—flagship of the Fleet of Valiant Prudence—in orbit over Reach, Operation: LEFT JAB distracted the Covenant fleet while the concurrent Operation: UPPER CUT destroyed the supercarrier.
