Presenting from McFarlane Toys, SPARTAN Gabriel Thorne, the main character of the SPARTAN Ops series of Halo 4 where he served as a rifleman in Fireteam Majestic.
SPARTAN IVs are not to be confused in with the cannon-fodder members of the SPARTAN III program which included Noble Team, as these were just soldiers given superior training in tactics along with Mjolnir power armor. They were literally released to die and delay the Covenant.
And not to be confused with the members of the SPARTAN II program from which John 117 hails. He was kidnapped as a child, subjected to training and genetic augmentation and then given Mjonir Power Armor - which also explains why he's so expensive. Modifying adults was cheaper. SPARTAN II's were still superior to SPARTAN IVs - though SPARTAN IV Mjolnir Generation 2 armor is superior to the Mjolnir armor issued to SPARTAN IIs.
But then, John 117 now wears a SPARTAN Mjolnir Generation 2 armor.
So he's superior in every way.
