Interesting fact ¹⁾.

All British shielded vehicles have a type of water bubbling vessel inside. This really fills two needs.

Making tea (or espresso in the event that you totally should).

Warming up the plasticised foil sacks that UK military proportions come in. They are intended to be drenched in heated water.

Protected vehicles are planned to have individuals within. On the off chance that you head outside, the trouble makers will shoot you. So you probably won't have the option to go outside when you need a cuppa (to set up a camp oven, etc).

Probably some UK reinforced vehicles have such a protected fluid containing vessel on the backside that can hold an entire heap of tea, or other beverage in the event that you totally should. Now and then the group join a plastic outdoors cup, hanging off it on a touch of string.

This is with the goal that the infantry outside the vehicle can open the tap and get a snappy swallow of tea at short notification. It's on the back for when the infantry are seeking shelter behind the vehicle. They can in this manner have tea when being taken shots at, much the same as the fellows inside. Hanging tight for an airstrike to dispose of the trouble makers? Break time.
