Ever tried this?

Things just need to be even. Nine chevrons is not even. Ten would be even. Eleven would be uneven. Now 12 would be OK. It is just too easy to get to 9 chevrons and why can't my superior-to- the-Timurid-and-Mongol troops get a chevron to show it! It could show up by having a piper to accompany my Scot's pikemen as they annihilate the Timurids at the gate and in the field.
