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. Newly inducted Spartans are required to use the Recruit-class armor for an individually determined time frame before requisitioning custom kits. The Prime skin is part of the Infinity Actual Kit recommended for Spartan-IV first contact and asymmetrical operations. ĭecades of combat experience with Mjolnir suits informed the design and electronics hardware architecture of the RECRUIT helmet. Testing for the GEN2 version was swiftly done, as by January 2553 a copy of the armor was onboard the UNSC Infinity. 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. The majority of the Recruit variants were manufactured by Hannibal Weapon Systems and tested at WG/Facility 93-00/Kotka. Whether this color scheme is common among all recently inducted SPARTAN-IVs is unknown. The standard color scheme for Recruit-equipped Spartans aboard the UNSC Infinity consists of orange-yellow stripes at various points, most notably along the center of the helmet, though the suit remains largely unpainted.

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