What's the point of machine guns and green paint if Sousa's assumptions are correct - that the IAC will never deploy tactical helicopters on overseas missions? Total waste. Keep the pretty white flying helmets and go back to royal blue flight suits and dayglo orange paint schemes in keeping with a service devoted more to air shows than military ops.
Never say never. The IAC should be prepared with the proper equipment, training and attitude to perform combat operations overseas, and there definetely should not be a formal prohibition against doing so. When conditions are right it will happen - probably out of dire necessity at short notice.
For example, as I alluded to earlier, imagine the hue and cry if Irish soldiers caught in an ambush or by an IED die because they couldn't be medevaced or reinforced at night in poor weather by the on-scene UN Mi-8's flown by Bulgarians. Or RW assets are unable to conduct ops to free Irish hostages on an overseas mission that are later killed; or a massacre of civilians a la Rwanda occurs; or any number of other unpleasant scenarios resulting from UN helos being unwilling or unable to do the job.
The right thing to do is a follow-on order for 4-5 A149's to provide the capability to deploy a 3-4 aircraft detachment as part of a multi-national force - preferably aligned, including combined training, with Nordic Plus EU Battlegroup assets = Swedish Super Pumas, Finnish NH-90's and Norwegian 412's. Pooling these assets solves the queston of support for multiple rotations over time - i.e., Finn and Irish air assets for one nine month rotation, followed by Swedish and Norwegian assets for the next, and so on.
Bear in mind a battalion task force is the basic building block for the EU BG's, with the ability to grow into brigade TF's. Given the world in which we unfortunately find ourselves, the BG's will deploy. If not Lebanon again, then Afghansitan, or Darfur, or Uganda, or Somalia again, or some place we haven't even heard of yet. Ireland will either contribute fully and effectively or it won't.
