This is why every British armored vehicle has tea-making gear
Tea has been an essential element of British culture for centuries, so it makes total sense that the British feature a tea kettle in the designs for their armored vehicles.
Since developing the 1950s-era Centurion Tank, UK-designed armored vehicles have featured a boiling-cooking apparatus, nominally designed for tea.
The reason for this nod to British tradition is actually much more pragmatic than just making teatime. Tommy tankers fighting in WWII France would leave their armored vehicles to brew tea by the side of the road.
It might be a little hard to make a proper thrust through the enemy-held hedgerows when most of your tankers stop to have a spot of proper British tea by the roadside at certain times of day. Not to mention the fact that the area was full of Nazis, bent on throwing English tankers back in their Channel.
This all came to a head on D-Day+6, when the British 22d Armored Brigade stopped outside Caen for morning tea, all the time being eyed by four hastily-assembled German Tigers.
War Is Boring’s pathos-filled account describes the tea party that ended with the British losing 14 tanks, nine half-tracks, four gun carriers and two anti-tank guns in 15 minutes.
A study done after the war found that 37 percent of all armor unit casualties occurred when the crew member was outside of the vehicle.
They won’t make that mistake again. The water boiler and ration heater in modern British tanks is a pretty nifty innovation. It guarantees access to hot food and water and keeps troops safely inside their armor.
A good idea, is a good idea, is a good idea — and the boiling vessel is a good idea. Whatever keeps tank crews inside their tanks is probably for the best.
