Zama, 202 BCE
A levy system survives Hannibal.
Hannibalic War, Gallic War as a political text, Dacia, and the Rhine-Danube as a standing campaign idea -- dated.
No siege-engine construction content.
Principles
Actium, 31 BCE
A civil war ends in a navy's photograph.
Adrianople, 378
A late army's public disaster.
Comitatenses / limitanei
Late field vs frontier categories in the sources and in modern debate. Read as a c. 6th century BCE-5th century CE in the West (East continues as Byzantine -- a sequel file) concept in Italy, then the Mediterranean and European-Near Eastern frontiers.
Vegetius
Late handbook English officers once read as if it were timeless -- it is not. Not a present instruction.

From Cannae (216 BCE) through Actium (31 BCE) to West's conventional end (476) in Italy, then the Mediterranean and European-Near Eastern frontiers. One sequence, not a staff overlay.
Scipio Africanus (Republican general) and Hannibal (Carthaginian general) sit at the centre of most English accounts; Vegetius and Constantine the Great correct the usual photograph.
Limits
Source limits
Figures such as "not one war -- a centuries-long institution; human cost is spread across conquests, civil wars, and frontier wars" stay in ranges because records are incomplete, political, or still closed. What were the Marian reforms? is answered as a band.
No how-to
Roman military is era-bounded force-structure history, not a live order of battle or mobilisation how-to.
Memory bias
English-language fame of Roman military and local memory in Italy, then the Mediterranean and European-Near Eastern frontiers are not the same map. Constantine the Great is often the correction the first photograph drops.
A column is propaganda. Read it as such.
Do not copy a civil-war march as a lesson in seizing a capital -- see coups pages for why that sentence is forbidden as method.
