[acrosome]

As a product of a military educational system, I'd support having specializations for Strategy such as (Grand) and (Operational). The latter probably needs to sub specialize by type (land, naval, etc.), though there is a lot of cross-training.

The real problem, as always, is in figuring out when you need to use Tactics and when you need to use Strategy (Operational). A fair rule of thumb for game purposes is probably something like "If you have to worry about logistics, it's Strategy."
