Strategy Note

As Romans: Use Plumbatarii + Comitatenses to hold, then Palatina to flank. Never fight Huns in open field without massive cavalry.
As Huns: Never dismount. Micro horse archers to kill generals, then mop up.
As Horde: Keep your Women of the Tribe alive – they're your future population.

Horde armies consist of huge numbers of "Warband" units. They have zero upkeep but very low morale.
As a Horde, you must sack a city immediately to survive.
As a Roman, do not fight Hordes in the open field early on; they outnumber you 3-to-1. Let them siege a city and use your superior heavy infantry to slaughter them at the gates.
