So I played around with the Volunteer Guard Day. If anyone is interested in what this is, you can find details here:
There doesn’t appear to be any achievements or rewards for it. It’s just a for-fun thing.
So far, it seems that you can only turn into guards at capital cities. Despite that, I checked out the Ogre guards at Brackenwall Village and Stonemaul Mound, and sadly they didn’t work.
However, there happens to be a couple of Ogre guards at Shattrath, as mentioned previously. This is the mob you /salute to turn into:
They’re using the old Ogre model, as opposed to the Draenor Ogre model, so they are missing animations such as the ability to mount, use a bow, and so on.
Also you can go to other areas and attack with this 24 Guard buff you get from saluting them. I think it wears off in instances, however.
I did a few size comparisons screenshots as usual:
This is without an elixir of Giant Growth. This was also done on this character before I saw there was no bow animation. So I hopped onto my Horde Arms Warrior to be more fitting.
This is with an elixir of giant growth, which…honestly, isn’t too bad in terms of height.
The rest also use an elixir of giant growth.
Model size comparison with a Tauren. Seems just about right to me. I wonder how manageable it would be for other aspects.
And a quick model size comparison to other player characters at the auction house.
I did take more screenshots, but I’m going to sort through them later and post them in another post. Right now, I wanted to spread the word for those interested in trying out being an Ogre too. This only lasts for one day, thus the need to get the word out ASAP.
Makes me wish I had organized an event involving this so we can have a bunch of Ogre guards bashing baddies for da Horde. Ah well, maybe another time…or maybe, we’ll be able to be real Horde Ogres someday!
I’ll post more screenshots later when I can. I may play with the event a bit more too if I get the time to do so. All I know is that it has made me REALLY want playable Horde Ogres more, and that it’s giving me some inspiration for in-game Ogre events in the future. 
Dream big, Ogre fans!
