Command Post
In The Royal Artillery, the CP is where the big brains live, cocooned in warmth and luxury at just the correct temperature to make sure everything is "just so" with the complex calculations.
If you want to upset the CP Officer, memorise the following phrase and call it over the net:
Fire Mission 6 guns, Danger Close, Co-ordinated Illuminating, Smoke, Linear, 1500 metres, Zero co-ordinate
In anything but The Royal Artillery the CP is usually the back of a Landy somewhere with a map in it.
