A land-based military vehicle 2, comprises a weapon firing control system 20, which requires direct user input to control, one or more other vehicle control systems 22, and a user interface 14 for facilitating interaction between a user 4 of the land-based military vehicle 2 and the one or more other vehicle control systems22. The user interface 14 is arranged to be functionally asymmetric, in that a user interaction with the interface 14 of a first functional level relates to an interaction between the interface and the one or more other vehicle control systems 22 of a second functional level, wherein the second functional level is greater than the first functional level. |
