That's a tremendously broad question that depends on many factors. The easy answer is - it depends. How much equipment is there? What are the arrangements for its maintenance? What is the amount and type of training expected to be done at the armouries v at the training centre? What type of unit and associated equipment is it? What is the configuration of the armouries and its storage facilities?
As a quick shot, if we look at today's ARes structure and the amount of equipment dedicated to them (even if increased) then the only logical system is one where the few number of F Ech vehicles is held and serviced at a training centre for pool usage while, at best we can hope for a few simulation trainers on the armoury floor.
The problem becomes even bigger if equipment for the ARes is issued at anywhere near baseline levels (i.e. the full TOE for an LSCO mobilization capability) so as to make them a mobilizable force. A Class A force and a 19th century armory system is not suitable for on-site storage or training.
