A friend attended the ALS (Army Language School, the predecessor of the DLI) in the early 1950s for Russian, and what he has described to me sounds quite similar. His course was for the Air Force: 6 hours per day, 5 days a week, for 22 weeks. The soldiers were given vocabulary and dialogues to memorize every day, and as is not surprising the classroom work was strictly regimented, with the same activities at the same hour each day. He says that their dialogues were not necessarily memorized and could be read in class, but the vocabulary was to be memorized each evening, and it was used right away in the classroom. He did not mention how many words were given per day.
He agreed very strongly w/ the observation that vocabulary was almost exclusively military. There were only a couple of dialogues that dealt w/ non-military matters: specifically, a young officer returned home for a wedding, which I think involved 2 dialogues from the 22 weeks. Even now, he said, he'll come across words learned at ALS that he's surprised to find have a different, "civilian" meaning from what he knows. That "полоса" means more than "landing strip" is an example he mentioned.
