Boiling Vessels (BV) for making hot tea, are standard military issue in UK
Similar to every British tank since the Centurion, and most other British AFVs, Challenger 2 contains a boiling vessel (BV) for water which can be used to brew tea, produce other hot beverages and heat boil-in-the-bag meals contained in ration packs.[12] This BV requirement is general for armoured vehicles of the British Armed Forces, and is unique to the armed forces of the UK.
