Triarii (singular: Triarius) were one of the elements of the early Roman military Manipular legions of the early Roman Republic (509 BC – 107 BC). They were the oldest and among the wealthiest men in the army, and could afford high quality equipment. They wore heavy metal armor and carried large shields, their usual position being the third battle line. They were equipped with spears.
During the Camillan era, they fought in a shallow phalanx formation, supported by light troops. In most battles triarii were not used because the lighter troops usually defeated the enemy before the triarii were committed to the battle. They were meant to be used as a decisive force in the battle, thus prompting an old Roman saying: 'It comes down to the triarii' (res ad triarios venit), which meant carrying on to the bitter end.
Triarii may have evolved from the old first class of the army under the Etruscan kings. The first class comprised the richest soldiers in the legion who were equipped with spears, breastplates and large shields, like heavy Greek hoplites. They served as heavy infantry in the early Roman army, and were used at the front of a very large phalanx formation. After a time, engagements with the Samnites and Gauls appear to have taught the Romans the importance of flexibility and the inadequacy of the phalanx on the rough, hilly ground of central Italy.
We enter now enter the world in troops of thousand men
An army of destruction, we'll force the end
We mark the lands with blood, in fire we prevail
We are tremendous, we are the end of days
We darken skies forever
We force the sun to ground
We are the thriving empires in our days to come
We're filling up the trenches with blood of thousand men
For you my mother, we will not return
Mother of pain
We will not return
Wrap your face in tears
We are ever marching
We dwell in consecration
We are the state of war
We drown the world today in sorrow and in pain
We're burning kingdoms
Inflaming hearts and minds
We rise and fall in heaven
We fall and rise again
We conquered Earth today with swords of light and fire
We are living torches, we are marching towards the sky
We are the legion, and we will worship sun
For you my mother, we will not return
Mother of pain
