Appointments in permanent reserve warrant officer grades shall be made in the same manner as is prescribed for regular warrant officer grades by section 571(b) of this title . Appointments as Reserves in permanent warrant officer grades are for an indefinite term and are held during the pleasure of the Secretary concerned. The amendments made by subsections (a) and (b) [amending this section and section 555 of this title ] apply to any appointment of a warrant officer or chief warrant officer on or after the effective date of this section [see Effective Date of 1985 Amendment note above].

The date of rank of an officer who receives an appointment under this paragraph is the date of rank for the officer’s appointment by warrant to that grade.”
