Besides the lorica segmentata and lorica hamata what did the romans use for body armour?
Also whats the difference between a manipular legion and a cohort one? as far as i can tell, they functioned almost the same, the hastatus and principes where not so different compared to marian legionnaires.
My last question is, where there triarii who fought with pila? i always thought they used the phalanx style but carried scutums instead of hoplons, but from a recent discussion with a friend he told me they also fought like the principes and hastatii (ie using pila not spears).
