UNSC Office of Naval Intelligence Special Warfare School

The UNSC Office of Naval Intelligence Special Warfare School is an elite training program jointly operated by the UNSC Office of Naval Intelligence and the UNSC Special Operations Command that is designed to train select personnel for special operations.
While its particulars remain highly classified, only a small percentage of initial students eventually graduate, and the training regiment is said to be physically and psychologically brutalizing, "breaking in" soldiers for their later roles as special forces commandoes. Graduation with highest honors from the Special Warfare School is a notable accomplishment in the special forces community, and gives the trainee the right to wear the black carbide knife on his / her breastplate.
Notable students of the Special Warfare School include Wakes and Delta-Two.
