The subsequent organisation of legions varied greatly over time but legions were typically composed of around five thousand soldiers. During much of the republican era, a legion was divided into three lines, each of ten maniples.
After the Marian Reforms and during the Principate period of the Roman empire, each legion numbered approximately 5,200 men, sometimes rising to 6,000. This diminished to as few as 1,000 men during the empire's twilight years.
A legion was nominally composed of 6,000 soldiers, and each legion was divided up into 10 cohorts, with each cohort containing 6 centuria. The centurion thus nominally commanded about 100 men, and there were 60 centurions in a legion.
During the Roman Empire, legion referred to a division of the army that numbered between 3,000 to 6,000 soldiers.
In the military operations of Lucius Cornelius Sulla and Julius Caesar, a legion was composed of 10 cohorts, with 4 cohorts in the first line and 3 each in the second and third lines. The 3,600 heavy infantry were supported by enough cavalry and light infantry to bring the legion's strength up to 6,000 men.
10 squads (contubernia - a tent group of generally 8 men) = a century, each commanded by a centurion = 80 men [note that the size of a century had diverged from its original, literal meaning of 100] 6 centuries = a cohort = 480 men. 10 cohorts = a legion = 4800 men.
The American Legion is the largest wartime veterans service organization with nearly 2 million members and more than 12,000 posts in communities throughout America.
The Roman legion was a highly disciplined, well-trained, and heavily armed body of infantry, which, in the first century AD, comprised between five and six thousand men (the exact number is not stated in the classical literature), all of whom were Roman citizens.
The Roman army was divided into legions of about 5,000 men. Contubernium: consisted of 8 men. Centuria: (century) was made up of 10 contubernium with a total of 80 men commanded by a centurion. Cohorts: (cohort) included 6 centurie, a total of 480 men.
Battalions consist of four to six companies and can include up to about 1,000 soldiers. They can conduct independent operations of limited scope and duration and are usually commanded by a lieutenant colonel.
Legion/Brigade—4 regiments (9,216 troopers) led by a senior clone commander and a Jedi General. Regiment—4 battalions (2,304 troopers) led by a clone battalion commander, clone regimental commander, and a Padawan Commander. Battalion—4 companies (576 troopers) led by a major, and a Clone Battalion Commander.

…of each line formed a cohort of 420 men; this was the Roman equivalent of a battalion. Ten cohorts made up the heavy-infantry strength of a legion, but 20 cohorts were usually combined with a small cavalry force and other supporting units into a little self-supporting army of about 10,000…
Three or four squads make up a platoon, which has 20 to 50 soldiers and is commanded by a lieutenant. Two or more platoons make up a company, which has 100 to 250 soldiers and is commanded by a captain or a major.
When at full strength, an infantry regiment normally comprised two field battalions of about 800 men each or 8–10 companies. In some armies, an independent regiment with fewer companies was labelled a demi-regiment. A cavalry regiment numbered 600 to 900 troopers, making up a single entity.
A division is a large military unit or formation, usually consisting of between 6,000 and 25,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.
Sub-units of the Roman legion
Contubernium – The smallest organized unit of soldiers in the Roman Army.
Legio XIII Gemina, in English the 13th Twin Legion was a legion of the Imperial Roman army. It was one of Julius Caesar's key units in Gaul and in the civil war, and was the legion with which he crossed the Rubicon in January, perhaps the 10th, 49 BC.
1. Legio V Macedonica: The Enduring Roman Legion. The Fifth Macedonian legion was one of the rare Roman legions that could trace its origin to the end of the Republic, while its end arrived at the dawn of the Middle Ages. This enduring legion was founded by Octavian (the later Emperor Augustus) in 43 BCE.
At its largest, the Roman army was made up of 30 legions, or over 150,000 soldiers. Counting the auxiliary soldiers, some estimate there were well over 1 million soldiers in the Roman army, so it really was a military force to be reckoned with.
This training combined with having the most advanced equipment at the time made the Roman army really powerful. The Roman army had many weapons and tactics that other armies hadn't even heard of before! They would use huge catapults which were able to fling rocks over distances of several hundred meters.
Height: 1.75M (5'8”) tall. have excellent vision and hearing. be able to read and write.
The legion was commanded by a legatus or legate. Aged around thirty, he would usually be a senator on a three-year appointment.
The legions just became the armies of local warlords, they had been made up of local forces more loyal to their local leaders rather than Rome for a long time (centuries). So in a sense they stopped to exist, in another sense they continued to exist, just under theoretically different high command.
