Spartan V ideas

Spartans IV are really nicely portrayed in Halo infinity
My idea of the next generation of Spartan is purely theoretical.
Spartan Vs may be just Spartan IVs but specialized with certain roles.
They may have to carry weapons or gear that are too large, or specialized for
normal Spartan IVS.
Spartan Vs may also be more like stealthy elites with energy swords.
Spartan IVs may be include teams like Osiris, but Spartan Vs may be new
more interesting Spartans, maybe more so than in Spartan Ops.
