The bulk of the Templar's military might was comprised of knights and sergeants. Although both classes of Templars were as likely to die in battle, the knight had a higher ranking within the Order.
Knights had to be men of noble birth and wore the white mantle that is the most familiar garment of the Order. Each knight was permitted one squire and three horses.
Sergeants did not have to be of noble birth and to show their lower rank, sergeants wore a black or brown mantle. They were given one horse and had no squires under their command.
