Sort of depends on your troop. As a young teenager we had to endure winter survivalist training which included building usable sleeping quarters in the sub-zero snow and spending the night in them, by yourself. Yes you could come back to the main building but you failed at the training if you did. Actual chance of freezing. They gave you a styrofoam cup half full of chili but otherwise you were on your own for sustenance too, including water. It did give me a sense of independence, but also a fear of the cold.
