Why these random letters??

I finally decided to 'research' the question of "Why these letters" in the arena.

This is what I found out.  But first you should know that there are two standards.  One being a small arena, with the letters you see in my arena. The second are the letters in the large arena.  This quote refers to the large arena:

The standard dressage arena letters are A-K-V-E-S-H-C-M-R-B-P-F. 

(There is speculation as to why these letters were chosen. Most commonly it is believed because the German cavalry had a 20 x 60 meter area in between the barracks which had the letters posted above the doors)

taken from the dressage wikipedia page.
