The shortened course does not mean a 'lesser' controller. Those ex-mil will have to pass all the exams and reach all the same standards as those who complete the 'full' course.
This has all been agreed with SRG (ATSSD) and Prospect, so I'm reliably informed.
As to the training at LACC and leap frogging the ab initio ATCO T & D's etc. Well the best guess is that ex-mil should be able to shave 6 to 8 months off of the normal time to obtain a single validation. So if I were a manager, given the rather huge shortfall in trained staff, I know who I would place at the head of the queue to get a bum in a seat ASAP. As to the disadvantage to those others in the training system, well thats something that the managers will have to address.
But then we all know what NATS managers are like!!!
