No you're just looking at things from one side.
The Army needs more CAS. You guys provide it. You're saying you have the means to provide it but can't afford to deploy it. From where I'm sitting something thats needed but can't be deployed due to cost is nothing more than a shiny toy wasting money for no return. You don't lose the capability as I'm not saying get rid of them all but you could probably bin half and use the money better elsewhere. Your justification is it might be needed in the Falklands in the future, nice but what about the war we're fighting today?
