Maybe I am one of the few to agree with Seagoon's opinion. Destroying a garrison would seem much better and much more immersive. To me it is not as much a point of religion, but of general ethics and gaming challenge (it seems kinda weird to have to bomb the civilian buildings every time). It is not really a huge issue the way it is now, but it could be better.
IMHO, it might be much more challenging and interesting if there were fewer building required destroyed to capture the "garrison" and the rest would be civilian buildings, maybe a hospital etc, which would actually give you minus points if you destroy them
