After a little bit of searching, I think I've found the fastest Epaulette mate possible, only taking 9 moves maximum!!! So if you are doing this solo on the same Xbox, that means the least amount of loading screens! 
If you do not know of this method that uses two accounts, it is explained better in many of the other mating technique solutions, but it consists of playing a game between two accounts on the same console, and going back to the main menu to switch the account you're on every time you want to make a move. It is a little time consuming, but faster than attempting to earn this achievement against the computer.
To start a game, make sure both accounts are on the same Xbox and are friends with each other, and that the dummy account has played at least one game against the computer (I couldn't get my dummy account to show up in the friends list if I didn't do this first). Then on the main account from the main menu, Single Game--->New Game--->Continue--->Opponent (Friend) (Dummy Account)--->Start Game
Since you cannot choose your own color, I've left solutions for both colors, in Algebraic and Expanded notation.
If your main account is playing White:
If your main account is playing Black:
Happy hunting and good luck!
