Further to my last:
After reading Loachman on Infanteer's 1st Wing thread I have a much better appreciation of his position. Hard to argue against him.
Maybe though.....
After I finished a_majoor's question by suggesting the Luftwaffe/Fallschirmjager as a model, and also deciding that blue suited soldiers falling from the sky wasn't quite what I had in mind another model occured to me: Royal Navy/Royal Marines, or for that matter US Navy/US Marines
In both these instances, although arguments can be, were and have been made that the "soldiers" (apologies to BBJ and Greenlid) should be army types one of the advantages in leaving within the control of the Navy and the Air Force is that it encourages the parent organization to figure out how to support and deploy them and how to use them.
Although there is still internal tensions over budget and whether driving a troopship is a real command it is harder for the parent service to deny that the task of supporting and delivering a ground force is their responsibility. Accordingly they, however reluctantly, pony up funds and personnel to support the task and, more enthusiastically, fight the political fight alongside the Army to secure the funds from Treasury. They also have the added carrot of being in command of a larger force with Army personnel under command, such as in the Falklands where Admiral Woodward was in overall command, with Maj Gen Moore (RM) in command of Land Forces and Brigadier Thompson (RM) i/c 3 Commando Brigade with 2 and 3 Para attached. This encourages the Navy to support the purchase of transports to deliver army troops with tanks and guns and stuff, to support their forces.
If you want jointery then make it jointery for all with two way streets.
Or do it like the US Marines and integrate ground training into the training of aircrew so that they know what the job on the ground entails and then make it clear that advancement will require ongoing training on the ground in support of, and in command of, ground operations. A guy in fighter, as far as the Army is concerned is nothing more than an Air Defence Gunner moving at a high rate of knots or else a gunner with a really long distance cannon and a penchant for riding the bullet to the target. If gunners can learn to command ground forces why not pilots?
