Comment 2 for bug 536548

I believe a per-building (both military and training site) setting with three possible settings, "Call highest-level soldier", "Call lowest-level soldier", "Don't care", should do the job. The settings would do exactly what the name implies, and if there are multiple equivalent choices available, the closest one would be picked.

I am against automatically ordering soldiers from military buildings. Any kind of automatism could do more bad than good (e.g. ejecting a soldier just before an attack), and it's easy enough to eject soldiers manually.
