Underuse of cavalry in the roman army

[Flavivs Aetivs]

The Late Roman Army saw an increased importance in Horsemen - where Horse Troops usually made pivitol moves - but infantry were the ones who continued to slog it out on foot, and in the end decided the battle. Cavalry at the time usually only had one role - it wasn't until the Sarmatians arrived that you see multi-role cavalry in Europe, and until around the time of the Huns that the Romans began using Lance-And-Bow cavalry.
