Roman Legionaries Then and Now?

 Two sets of the backbone of Roman power, nineteen centuries apart, the dreaded Legionaries. 

1st Century C.E. One of the most feared sights on the battlefield, a unit of Roman Legionaries on the attack. With the sure knowledge that they were the best soldiers in the World, these Imperial Legionnaires fear no one.  After a flight of pilums, it's time to hit the foes with the Gladius. "Death to the enemies of the Empire, and glory for the Legion." For almost two centuries, the legionaries of Rome enforced the "Pax Romana" (Peace of Rome) a time where most of Western Europe and the countries of the Mediterranean Sea were at peace, without a major war. An accomplishment that has never been duplicated to this very day.

Before the countless hordes of "Barbarian" invaders arrived in later centuries, it was often the truth that the greatest danger to a unit of Roman legionaries was another unit of Roman legionaries due to the frequent wars between rival factions for control of the Empire.  But that is a "Post Pax Romana" time, so for now these elites of Roman rule the Euro-Mediterranean World.

1900+ years later and a new force of Roman elite warriors has appeared in the Post Great War World.
As seen in this patrol from the hidden city-state of Novum Imperium Romanum Consularis Julius Augusts XXIII (New Roman Empire of Consul Julius Augusts XXIII) which protects the Empires hidden nature. Strangers they locate are either eliminated or made slaves of the Imperium. They are armed with the latest in Roman small arms weapons technology. 

Centurion Hadrius Corfortium is armed with a Electi Parvus Sagitta Dirigentes (Elite Small Arrow Shooting i.e. heavy submachinegun). Four troopers have the Parvus Sagitta Dirigentes (Small Arrow Shooting-i.e. a Submachinegun) Two have the Gravisbus Sagitta Dirigentis (Heavy Arrow Shooting-i.e. Assualt Rifle). Stong fire support is given by a Multi Sagittam  Dirigentis (Many Arrow Shooting-i.e Light Machinegun). While for serious problems the very deadly Constantinus Ignis Iaculator (Constantin's Fire Thrower-i.e. Flame Thrower) is always ready to burn away troublesome intruders. For defense, their Galea (Helmet), Lorica Segmentata (Body Armor), and Scutum (Large Shield) are made of Sagitta Probationem Metallum ("Bullet Proof" Metal).The Signifer is not just a standard, it is also the squads Missis Aer Nutiis Acciprentis (radio Transmitter/Receiver) The insulated helmet allows two-way communication with command base. 

Soon the day will come when the Novum Imperium Romanum will make itself known and the World will again tremble under the trod of Romes Legionnaires!
