Operation: HYPODERMIC was an effort by the Office of Naval Intelligence to collect information concerning the Covenant between January 2532 and August 2552. In this time dozens of Prowlers were deployed. HYPODERMIC was cancelled following the Fall of Reach. The word hypodermic means "under the skin."
