MR the british did often in WWII, they looked at their watch a said it was time for a brew. Maybe a reason why every British tank since the Centurion, and most other British AFVs, Challenger 2 contains a boiling vessel (BV) also known as a kettle or bivvie 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.
If I am correct, a british armour group was destroyed by german units in WWII as they were caught haveing a tea break during battle. = sudden death.
