P1
as said above, its your appraisal of the subject.
There is no choice about whether or not the want to 'sign' it electrically, the subject can use the comments box to refute anything if they choose to.
Refer them to P1 for some career guidance on obeying lawful instructions, I expected all 'my' SNCOs to be able to stand up for themselves when necessary but it appears that this subject did not take in the SJAR lesson on promotion courses.
Also as above, if its true leave it in, if were happy when you wrote it don't be swayed.
