Battle of Meridian

The Battle of Meridian was a conflict between UNSC and Covenant forces on the planet Meridian. The first prototype for the HRUNTING/YGGDRASIL Mark IX "Mantis" ADS engaged in an action known as the "Cherbourg Run", in which it successfully engaged 18 heavily guarded Type-27 Anti Aircraft Cannons, also known as "Mantis". The success of the prototype in the "Cherbourg Run" is one of the theories of why the walker was eventually called "Mantis".
