The British fascination for tea has, historically, not been without consequence.
During the end of WWII, there were incidents of British soldiers leaving their tanks for a break - and to make tea - only to be ambushed because it is the point at which tank crews are weakest.
So from 1945, British tanks were equipped with ‘boiling vessels’. This is for heating water inside the tank, which is for heating rations, amongst other things, but it has also lead to the claim that British tanks are explicitly equipped with tea-making facilities. It is - technically - true that tanks ship with tea-making facilities but it wasn’t the point of the exercise.
