Frost

Master Sergeant Frost is a Non-commissioned officer in the UNSC Marine Corps and an Orbital Drop Shock Trooper in the 105th ODST Division. She was the superior officer of Dutch and Romeo during Operation: FIRESIDE in 2552.

Biography
It is unknown how long Frost led her ODST platoon, but it is clear that she had commanded Romeo and Dutch for quite some time. When Dutch informed her that he planned to transfer in order to spend time with Gretchen, she allowed Dutch and Romeo more time off-duty, showing her clear understanding of the strong bond the men had.

After the body of Charles was found on Ariel, she ordered that the Marines split into two-man scouting squads. She paired up with Michaels. When it appeared that the generator complex was overloading, she ordered a retreat, reluctantly falling back even though Dutch, Romeo, Higgins, and Campbell had not returned from scouting. Frost then ordered that the remaining ODSTs move to the other dig site, theorizing that the civilians may have moved there.

Personality and Traits
True to her name, Frost tries to remain cold and unattached to the troopers under her command, at least when she is in front of those under her command. However, she privately grieves for them.
