The Mk 1 Aggrevator Mechanized suit, or Mk 1 Agg Suit for short, is a UNSC Mech walker used during the early stages of the Post War Era, and specifically the Syphodyte Campaign. Its dons 10 cm of Titanium grade C armor, and two heavy machine guns, as well as a shoulder mounted rocket launcher. The Aggrevator contains 5 days worth of Oxygen, medical supplies, food and ammunition, and can keep a soldier alive in radioactive conditions. Its firsts use was during OPERATION: NEW HOME LOST where it was proven useful for urban combat and easy to use. Two months after the operation, the company, Generation Technology, were asked to build a second mech, the Mk 2, which was just as successful, and used alongside the first for the rest of the Syphodyte Campaign.
