126?!! Back then nobody even lived past 80. The healthcare sucked and there were no machines to help them.
But ok, makes it easier for another nation to conquer an old man and his army of old men.
Romulus walked outside, he breathed in the air, "Ahh... smell that air, Marcus. It is the smell of money." Romulus has just signed two lucrative trading contracts that promises to bring extra money and people to Rome. He walked over to the barracks to look over his soldiers.
An officer stood up and saluted, Romulus saluted and headed inside where he saw the soldiers laying down and watching a comic do his stuff. Every one of them stood and saluted when the officer bellowed, "Attention!" Romulus looked at the soldiers and muttered to himself, "This army is in dire need of new weapons and armor." He turned and left the building.
Once at the palace he sat down and grabbed a scroll, and a pen with ink, after several attempt he issued his final draft,

1 Legion constists of the following; Legate Commander, Pilitus Centurion

60 cohorts of 100 men each. Headed by Centurions.
When on march:
Lead cohort to be chosen by Legate Commander will lead the column, followed by the rest of the Maniple. The other maniples will follow suit as Legate Commander sees fit. Pilitus Centurion makes sure Legion is following protocal.
When in camp:
Legate Commander HQ and tent is in center of camp.
Pilitus Centurion is on his right, with the Tribunes tents on the left.
Blacksmith across the street, flanked by the stables (takes care of horses and cattle)
Barracks line the fort in straight rows east-west, for easy mustering and departure of fort in times of peril.
Doctor's tent lies next to the Pilitus Centurion.
2 cohorts from 2 maniples man the defences for 2 hours before being relieved by 2 new cohorts from other maniples.
When in battle:
Each maniple is arranged side by side, facing the enemy. Each maniple may choose which cohort will take the place of honor on the frontlines. The Legate commander will choose which maniple takes the right flank, the place of honor.
Once battle has been initiated each cohort will fight for 30 minutes before retreating to the end of the maniple and the next in line steps foward and keeps the fight going, this is continous until battle ends.
Once battle ends, each cohort must reform at their standard and be counted, each centurion then takes his count to the Tribunes who in turn takes it to the Pilitus Centurion who will tell the Legate Commander.
The fearsome Roman Legion ready for action.
EDITED: Forgot to add, the legions will be armed and protected by the best armor and weapons at the time. When new weapons are found the Legions will be armed with it.
