At the Battle of Cannae, did the Romans have the advantage of Gaius Marius's military reforms?:

The Battle of Cannae took place in 216 BC during the Second Punic War, long before Gaius Marius's military reforms, which occurred in the late 2nd century BC (specifically around 107 BC). Therefore, the Romans did not have the advantage of Marius's reforms at the time of the Battle of Cannae. At Cannae, the Roman army was primarily composed of citizen-soldiers who were part of the traditional Roman military structure. Marius's reforms, which included the recruitment of landless citizens and the establishment of a more professional standing army, were not implemented until nearly a century later. Consequently, the Roman forces at Cannae were not influenced by these later military innovations. In summary, the Romans did not benefit from Gaius Marius's military reforms during the Battle of Cannae.
