The Band will come in two parts, cavalry and foot. The foot will be pikes, with higher discipline, training and maybe better attack then others. Tha cavalry will be like mounted nobles, buit mroe disciplined I assume.

And highly trained and diciplined... that i what I call elite...

And IMO, what mat did was that he united armies of different nations, and used their qualties in a way they fitted... But that is just me... Remember that they still say that they "belong" to different nobles. Mat is waht unite them.
