WRT:
Problems integrating Old Dara Happan Legions of 1111 men with new Lunar
Legions of 2450 + 1 General (optionally + 7 senior officers).
Since the Lunar Legion is composed of 7 cohorts of 350 men I would
suspect that this breaks down into 3 or 6 phalanx cohorts of heavy
infantry who who fight together (unit size = 1050 men which is the
same size as the DH phalanx in practice as these units were almost
NEVER at 100% manning levels). In addition to the heavy infantry
there might be up to 3 cohorts of Auxiliaries. In addition to
auxiliaries there might be cavalry or SPECIALIST cohorts. My view
is that there would never be more than 1 specialist cohort and these
would include Magical Types, Engineers and other exotics. Thus on
the field the Lunar Legion is treated as 1 or 2 phalanxes with
other loosly attached troops to cover flanks or create or exploit
weaknesses in the enemy line.
So integration is not a problem and the new Lunar legions have the
advantage of being self contained units with the ability to fight
smaller scale engagements without having to rely on other troops to
fulfill non-phalanx roles.
