What attracts you to Late Rome?

[Frank]

Thank you guys for your recommendations for monographies about the late roman army. I guess I will start with:
Hugh Elton, Warfare in Roman Europe, AD 350-425 and
Martinus Johannes Nicasie, Twilight of empire: The Roman army from the reign of Diocletian until the Battle of Adrianople
These two books seem to match my requirements.

Usually I am more interested in history of law & constitution, administration, finance & taxation, economy and society. But, I am very interested in the late roman army, too. I guess its organisation, structure and leadership was superior to the late republican or early empires army. Or let's say more appropriate to face the new challenges. At least before the desastrous battles at Adrianopel and Frigidus which lead to another change. Because the enemies they faced and defeated more than once were far superior compared to earlier times.

I like to learn more about the internals of this underestimated army. For the principate there are good books and articles showing some details of the command structure like Domaszewski, Birley, Breeze, Dobson, Speidel. But I did not find such detailed analysis for the late empire so far. I hope your recomendations will help me in this department.
