RECRUIT-class Mjolnir

RECRUIT-class Mjolnir is the standard-issue MJOLNIR GEN2 armor set manufactured by Hannibal Weapon Systems and Materials Group. It is the standard armor for all newly recruited SPARTAN-IV personnel.

Specifications
The reactor is covered by a "Class-A hardened reactor case". The shoulders are called "Common solid-plate pauldrons". There is a power conduit on the cuisse. The feet have segmented plates to increase mobility. The armor is designed to cope with the strain and duress experienced by newly augmented Spartan-IV.

The standard color scheme for Recruit-equipped Spartans aboard the consists of orange-yellow stripes at various points, most notably along the center of the helmet, though the suit remains largely unpainted. Whether this color scheme is common among all recently inducted SPARTAN-IVs is unknown.

Development History
The majority of the Recruit variants were manufactured by Hannibal Weapon Systems and tested at WG/Facility 93-00/Kotka. Both the forearms and greaves were manufactured by the Materials Group, with the forearms tested at FFG-045's combat lab, and the greaves manufactured on Chi Ceti IV. Testing for the GEN2 version was swiftly done, as by January 2553 a copy of the armor was onboard the.

Decades of combat experience with Mjolnir suits informed the design and electronics hardware architecture of the RECRUIT helmet.

Skins
The Prime skin is part of the Infinity Actual Kit recommended for Spartan-IV first contact and asymmetrical operations.

Usage
Newly inducted Spartans are required to use the Recruit-class armor for an individually determined time frame before requisitioning custom kits. The armor's performance consistency raises eyebrows among the more experienced Spartans, however, and despite its popularity, many Spartan-IVs opt to diversify the armor with other variants.

Spartans in the Recruit variant armor were sold as toys. One child had painted his Recruit Spartan action figure to resemble the Master Chief.

Trivia

 * In Halo 4, the Recruit right shoulder and forearms available to the player in multiplayer are different from those seen elsewhere in the game, such as on SPARTAN-IV NPCs in campaign and on characters in the Spartan Ops cutscenes. Curiously, the SPARTAN-IVs in Halo 4's campaign appear to be wearing what the game classifies as Ricochet forearms.
