The hypothetical situation pose to the Green Team, a team member is separated from the team when the parachute was directed to the other side of the mountain, actually occurred to Ray (Neil Brown Jr.) in My Life for Yours (2019)
When Ray is speaking to Chief Warrant Officer Mack, Mack jokes that people are often confused as to who warrant officers are and what they do since they are between enlisted and officers. In the US military warrant officers are rated as officers above all non-commissioned officers but subordinate to all commissioned officers. Warrant officers are highly skilled specialty officers whose primary job is to serve as technical experts providing valuable skills, guidance, and expertise to commanders and organizations in their particular field. In the Navy warrant officers are selected from the chief petty officer grades (E-7 through E-9), to be considered as a candidate they must have a minimum of 14 years in-service. Appointment to the rank of Warrant Officer One (W-1) requires sponsorship by a Chief Warrant Officer 3 (or above) or a commissioned officer, candidates for W-1 are usually selected by the Secretary of the Navy and sometimes the President. Advancement to the Chief Warrant Officer ranks (CW-2 to CW-5) requires a warrant commissioned directly by the President. To be considered for advancement from one grade of warrant officer to the next requires at least 33 months in-service at grade, so to advance from Warrant Officer One to Chief Warrant Officer Two requires 33 months service as a Warrant Officer One. Chief Warrant Officer 5 (CWO-5) is the highest warrant officer rank in the US military, it is reserved for only the most skilled and experienced warrant officers, only 5% of warrant officers make it to the rank of CWO-5.
