Doc Sloan Ritual Kappa Alpha Psi Rar File

As for "RAR," if it's related to the Red Army Faction, that's a different context, but given the other terms, more likely "RAR" here is an acronym within Freemasonry or a related organization. Maybe the Royal Arch Ritual (RAR)? The Royal Arch is part of the York Rite, which is a separate branch from the Scottish Rite. So perhaps there's confusion between different Masonic rites here.
