GROPOS is indeed one of those fan favorite episodes, I think because of that rare glimpse into other aspects of military life in that universe. Compare it to "The Siege of AR-558". The episodes are very different in many respects, but.... in each you get to see a side of the conflicts that normally is hidden or forgotten.
