British tanks have hot water boilers for brewing tea

Drinking tea is undoubtedly a key habit in British culture. Because of that, British people have initiated a practical way of having tea available more often, even when they are in the army!

British tanks contain a boiling vessel also known as a kettle  which can be used to brew tea, produce other hot beverages and heat boil-in-the-bag meals contained in ration packs.

Those hot water boilers are general for armoured vehicles of the British Armed Forces, and they are unique to the armed forces of the UK.
