MWP-6 'Messmier' mobile weapons platform

The MWP-6 'Messmier' mobile weapons platform was a multi-purpose gun platform used by the Covenant of Allied Powers and the Grand Initiative during the Eternal Heresy.

The Messmier is the most potent weapon in the Covenant’s arsenal. It first saw action during the Arterus campaign in limited numbers, but now is a symbol of Covenant might. Its combination of weaponry mixed with its incredible defensive systems makes it a very difficult foe to contend with.
