The first cohort of any legion were its elite troops. So too the sixth cohort consisted of "the finest of the young men", the eighth contained "selected troops", the tenth cohort "good troops".


The weakest cohorts were the 2nd, 4th, 7th and the 9th cohorts. It was in the 7th and 9th cohorts one would expect to find recruits in training.

Auxiliary Infantryman

An auxiliary infantryman of the the first century AD. His armour and equipment was decidedly inferior to that of the legionary
 
 

Syrian Auxiliary Archer
 
The eastern provinces were particularly known for their archers, using powerful composite bows. Syrian archers should serve across the empire as auxiliary forces.
Cavalryman
A typical Roman cavalryman, armed with large oval shield and lance, wearing a helmet and chain mail, he rode without stirrups.

Imperial Legionary
A legionary wearing the famous banded armour, the lorica segmentata, and the typical imperial 'Gallic' helmet. Also he bears the famous large square shield.
Centurion
The centurion's armour varied widely, perhaps it was even a matter of individual choice. The centurion depicted wears chain mail. However, the horsehair crest across his helmet, along with his cape, was what made him easily recognizable by everyone as a officer of considerable rank.


Note also the vine rod he holds in his hand. A further insignia of his rank and one he would happily use to beat unruly soldiers with to enforce discipline.
