Okay, here's the quick and dirty on FITREPs...
- No 1 of 1 EP? No breakout EP? highwater trait average <= RSCA? You are almost certainly now non-due-course.
- You may have to ask your CO their RSCA. They don't have to give it to you.
- Block 41 needs to recommend you for CO or Flag early and often; otherwise is a negative signal.
- Block 42 first and last line are a little important. The middle truly does not matter.
With this knowledge you should take action by:
- If not given, ask for CO's RSCA every time you debrief a FITREP.
- Put "Flag Officer" and "CO Afloat" in Block 41 starting with your first observable FITREP.
There's other stylistic things - document your performance with hard metrics, etc. - but that's covered a lot. The other stuff above isn't really covered much.
