The first two units were both done as mounted Templar Sergeants. In the long term I plan on getting some of the new Templar-style knights from Baccus, so I thought these would make good auxiliaries. I mounted them 5 to a stand in line to make them readily distinguishable from my 'shock' cavalry stands.
For the next unit, I opted to do a similar unit from the Knights of Calatrava. I really like the scheme and they allow me to field some forces at the scale for Spanish battles as well.
I have two more units of Crusader Knights on the table to complete the set. Thanks to you Secret Santa, good pick!
