High Commander Tier Blackbane to be exact (although ‘Blackbane’ may change, it was just a placeholder for him years ago), just one of a few high commanders directly under the Emperor, and also happens to be the father of Celsus (pronounced sell-sus). White coat, deep black mane.
 
Plus a look at his face weapon, the equines answer to the common sword. (someone give me a better name than ‘Face-Weapon’ please…)
 
High Commander = his rank  
Tier = his name  
Blackbane = his given title (’cause he did some badass stuff I guess)
 
 
From my upcoming webcomic series: Honing Equestria
 
If you want to get a taste (albeit a very small one) of what my webcomic is going to be all about then hop on over to fimfiction where I’ve written up a small and very unrevealing fic on the first few pages of the eventual comic: http://www.fimfiction.net/story/230538/honing-equestria
