No worries at all. Here are a couple of my comments on what a gate ward is: link1, link2 (people ask about it a lot). So it may contain some... guards-related buildings (barracks, armories, a gatehouse itself etc), but definitely not only them. Like with the most of other ward types the name of this one is supposed to be treated as a hint, not as a literal explanation what is there. Also I'm planning to replace them all with something more subtle in the future.
