The Roman infantry of the fourth century used defenses inferior to those of their predecessors.
The economic crises had forced to cheapen the costs of armament production.
On the other hand the adversaries against whom they faced neither used a great defensive equipment, if we discarded the heavy cavalry parta.
The usual appearance of a Roman soldier had varied. They wore "braccae" (ankle-length calf with a clear barbaric influence) and the tunics were long-sleeved and round-necked.
The different designs of the shoulders and the breasts of the tunics, as well as some circular insignia sewn in the skirt of the same, identified the different units.
The helmet is of cheap production and was produced by stamping two quarters of sphere that joined by rivets by means of a central border, covered the skull of the soldier, while cheeks and coversuits were independent and articulated parts.
They probably had Persian influence.
