You have missed my point. Read the sentence again. The 'we' is collective and refers to the RAF. Of course we (the RAF) can provide effect - and do it from home base; Bruggen based Tornados delivered kinetic effects accross Serbia and early UK based Bomber Command produced both kenetic and non-kinetic effects across a significant proportion of the European mainland.

You are confusing war fighting with soldiering. You do land combat (with some arms doing close combat); however, that is not the totallity of war fighting. In happens on a far wider scale than the one that exists within the significant geographical constraints of the LAND component.
