Their uniforms are very similar of Vorpal Soldiers, except theirs are red. They have the same black boots and the same black mouth piece. Their goggles are also red instead of green.
One of the few differences between them is that the gloves of the Spartan Soldiers do cover their fingers.
After Omega and Xero manage to escape and steal two Cervical Armors, regular infantry proves to be insufficient. As a consequence, MBORF decides to deploy more advanced units, Spartan Soldiers being one of them.Spartan soldiers attack Omega first in the metro station. They use their shields in order to cover several Rank 3 Soldiers. Although their shields appear to be impervious to damage, Omega manages to overpower them with his Armadillo. Once the formation is broken, Omega is able to take them down easily one by one.
Xero is also assaulted by some of them in the park. However, they prove to be inefficient to deal with the cyborg, as his incredible speed makes him too fast for any MBORF soldier.
