Roman legions in imperial time?

[VeniVidiVici]

were there hastati, principes, and triarii as a main heavy infantry unit in imperial time just like republic?

 

from wat i kno, there werent hastati,principes, and triarii. but there were just plain 'roman legions', no specific division

 

is tat true or were there three lines in imperial time too?

 

 

oh and Lorica segmentata was in imperial time only, eh?

 

in republic legionaries wore just breastplate and chain mail, right?

[Divi Filius]

The classical "Polybian Legions", as they are often called, died under the late Republic. There were no Hastati, Principes, Triarii divisions. In their stead the new legions were rather uniform: all carrying the same weapons. This, however, was not always so. In Tacitus we read that the Rhine legions had adopted Germanic styles of warfare, and wore similar clothing. Also, auxiliaries usually gave the imperial legion their own share diversity.

 

The legions themselves, however, had a great amount of diversity as they often molded to the environment they were placed in.

 

in republic legionaries wore just breastplate and chain mail, right?

 

The Principes and the Triarii wore chain mail, while the hastati(the first line) wore a small breast plate.

 

oh and Lorica segmentata was in imperial time only, eh?

 

Yes, under varying periods. It wasnt exclusive tho, and nor was it universal.

 

is tat true or were there three lines in imperial time too?

 

I believe the Romans did retain their traditional three line formation. However the imperial legions were not uniform and so could be more flexible.
