Only when there is a need for assets to be permanently attributed to organic tasks, like ship defence or firepower for lightly equipped troops (e.g. the USMC), are aircraft directly allocated to those units. A luxury the UK cannot afford as we have insufficient resources to give each of the RN or Army its own private air force. Ultimately, such a decision would cost more money or result in reducing overall effectiveness – with the obvious results.
