Gotta hand it to the British; they have their priorities right:

From Wikipedia:
>Like 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.[8] This BV requirement is general for >armoured vehicles of the British Armed Forces, and is one such >requirement almost unique to the Armed forces of the UK.

Here; everything stops for tea!
