Manipular legion
Mid-Republican formation -- a historical structure, not a reenactment drill. A founding or preface structure of Roman military.
Levy legion, allied alae, imperial long-service legions and auxilia, imperial fleets, late field/frontier split -- historical categories.
Not a reenactment ORBAT and not a kit shopping list.
Systems
Limes
Frontier system as a modern historians' word for a dated practice.
Comitatenses / limitanei
Late field vs frontier categories in the sources and in modern debate. A civil-military or alliance bargain -- dated, not a live chart.
Hannibal
The opponent who made Roman structure visible at Cannae and after. Not a Roman officer -- necessary on this page.
Zama, 202 BCE
A levy system survives Hannibal.
No live ORBAT
Roman military is era-bounded force-structure history in Italy, then the Mediterranean and European-Near Eastern frontiers. Cost band of related wars: not one war -- a centuries-long institution; human cost is spread across conquests, civil wars, and frontier wars.
