Warrior Ancient and Medieval Rules

Hi Jon. Had a question regarding mixing elements in a command unit.

The front rank of the unit is the CinC + 3 Reg A SHC L,B,sh

The rear rank of the unit is EHC, L,B,sh.

Is this legal?

From the General concepts in front of the army books, it says that
Generals can mix into units, as long as they are the same order.

SHC are close order. EHC are loose order.

So this is illegal under most circumstances (the Timurids being an
exception due to list rule)

Or am I missing something again?

Thanks,
