Hi I think there might be a cut paste error,
The Rear rank Sergeants are Average, CL, DC, ME and the Separate Sergeants are Superior, DC, ME, the exact opposite of the previous versions.
All other Crusader list, County of Edessa, 1st Crusader and Outremer states all reverse the above and the Superior DC without CL are the rear ranks
You may be right here - they look to have been swapped and we missed it :P
Yes, the two lines should be reversed. I have added this to the 2020.01 Errata.
