Can't find the source, but I recall one of the RT designers saying Space Marines were a parody of Starship Troopers.
RT is packed with in-jokes and British humour, but the system isn't a parody of other systems; so, I'd say the background is somewhere between pastiche and homage, but the book isn't more parody than anything else overall.
