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. This BV requirement is general for armoured vehicles of the British Armed Forces, and is unique to the armed forces of the UK. Don't forget to check out our Kickstarter Campaign!
