Another phrase from another issue of the same TV show . A private in a hospital in Vietnam is telling a story and says "We were on short time". This puzzled me, because when people say that they are on short time this usually means that they are on short hours. It obviously cannot apply here: combat duty is always a full-time proposition.
So I suppose it means something else here. As I guess, he wanted to say that he was drafted for a specific period of time (maybe 2 years or so) which was shorter than the time served by people who volunteered and signed a contract. Can anyone confirm/disprove this? It was 1966. What were different terms of service back then? Did the drafted people actually serve for a shorter time than those who signed a contract?
And another question: the same soldier says they were "a couple clicks from the river". Since when does the US army measure distances in kilometers? Is it because of the NATO standards?
