Final answer:
When communicating direct to a CAS platform without a JTAC or FAC(A), the observer must state "I am not a JTAC" or "I am a JFO" to clarify their role.
Step-by-step explanation:
This question is related to communication protocols used in CAS platforms, specifically when a JTAC or FAC(A) is not available. When communicating directly to a CAS platform without a JTAC or FAC(A) present, the observer should state "I am not a JTAC" or "I am a JFO" to clarify their role and level of authorization. This allows the receiving end to understand the level of expertise and support they can provide.
