Because the substring corresponding to the \5 backreference can be 4,
5, or 6 characters in length, I'm not sure what you're talking about
when you say "1, 2, or 3 characters after the RRS, DPS, or RCM values".
Would, for example, an "RRS" substring be part of the \3 or the \5
backreference in

    ^(....[0-9][0-9]|....[0-9]) (K|T|P|N)(...)(.*)/p(....|.....|......)$

Incidentally, because the "(.*)" substring is never referenced via a 
backreference, the above can be simplified to

    ^....[0-9][0-9]|....[0-9] (K|T|P|N)(...).*/p(....|.....|......)$

changing the \3 and \5 backreference to \2 and \3, respectively.
