Screening: A screening level of O is a Space Prototype and is only used with RHA O. See Table 8 on page 1 1 and Table 9 on page 12 for more information. 3. RHA: Interpoint model numbers use an “O” in the RHA designator position to indicate the “-” (dash) RHA level of MIL-PRF-38534, which is defined as “no RHA.” RHA O is only available with Screening level O.
