It seems to me that Traveller deals with Empires, with the Great Game of Nations, with Imperialism, and with Warfare, all topics which in varying degrees involve today's major powers and consequently their military forces. Thus (in some way) the game represents a variation of the reality. At the same time it offers the familiar, it offers the exotic - aliens, mind-bending bad guys, etc.
Interestingly, maybe because it is a university town, where I went to school, the gaming group there had a fair weighting of officers. Moreso now, because one of my friends went to Royal Military College (as a civilian, though he was a Sgt. in the Reserves... if he'd worn his uniform, he'd have been the only NCM at graduation and him getting a "Master of War Studies" degree was neat). After that, and after working on the Joint Space Support Team and at the Peace Support Training Center (peacekeeper and UNMO training), he had a bunch of officer friends who then blended into our regular gaming group, which had a Navy Lt. and an Army 2Lt. So now we have a bunch of officers, mostly 02 or 03.
