There have been some very valid points made in this thread, I have to agree with many of them. As it is now the ruleset for enforcing RP is a blanket that goes across pretty much every role for the USCM side and somewhat for the Xenos. Because of this it has very quickly become 'pick and choose' in terms of deciding what is LRP, MRP, HRP and so forth. Personally, I have felt that a rank rework could fix a lot of problems and potentially make it easier to enforce RP and not have heavy enforcement on roles that do not matter as much. I made a chart to frankly show my opinion on how things should be looked at and enforced by staff:

Each role comes from its own field.
Officers obviously going through a more formal Officer Acadamy, being taught formal etiquette and such. They should be expected to not be acting like spazzes but rather as a role that is serious and dedicated to the USCM/UA, Staff should ensure they are not acting dumb in these roles. Not full MILSIM but actually believable they are officers who deserve respect for their role.
Then there are
doctors/SLs/MTs/CL. College/NCO training/Trade school educated. They can be dumb frankly but are expected to do their jobs successfully be it surgery, loading the OB, or leading a squad. As long as they do that then they can get in whatever brawl or mischief they want frankly and get handled by MPs as long as its not griefing a person's round.
Finally
marines, they should be hands off from staff unless they are full out griefing/rulebreaking. Nothing should be wrong with a brawl between marines, squads, ect. 90% of the time they deploy and they are not seen again shipside so its not a big deal.
A rank rework I believe was in the past planned for potential switching of shipside roles to the Navy and groundside remaining marines. I think it would be a good distinguishment and Marines could see less RP enforcement by staff to allow them to do their own thing and foster their own RP in combat and the naval side being expected to maintain certain standards shipside since they are not 90% in combat like maintaining SOP and that sort of stuff for MPs to enforce.
