What's up with the (P) at the end of the rank ? Yes I know what it means. But when did it become part of a persons Rank ?

According to regulation, promotable status is not to be used in correspondence, nor is it a part of their rank or a rank unto itself.

Sounds like this is a rehash of the multiple threads already addressing this topic.

BTW ... No, I don't use (P) after my name in my signature block, etc. I just checked the block on RP that said I was "Currently Promotable".

AR 25-50
Chapter 6-5 Personnel on Active Duty
paragraph c(2) Do not use the “(P)” (meaning that the signer is promotable) as part of a signature block on Army correspondence unless it benefits or enhances the image of the Army. However, it may be used in an address for such things as congratulatory notes.

That being said I think those that do it tend to think that the addition of the "P" gives them some unfounded additional power or authority.
