These would be destroyed along with the Henry Lamb Research Outpost in 2559. When an expedition returned to Installation 00 in 2558, they brought several Mantis' with them for site security. He used one again during the Didact's attack on Ivanoff Research Station. When the UNSC Infinity crashed on Requiem in 2557, the Master Chief used one to help clear parts of the ship of Jul 'Mdama's Covenant. The Mantis has also been used by a few notable people. It was given the nickname Mantis because of its ability to ambush 18 heavily guarded Type-27 'Mantis' Anti-Aircraft Cannons during the Battle of Meridian on the legendary 'Cherbourg Run.' The Mantis first entered service in 2403.
