Final answer:
The legionary helmet was uncomfortable and often obstructed the hearing and vision of the soldier.
Step-by-step explanation:
The statement that the legionary helmet was uncomfortable and often obstructed the hearing and vision of the soldier is True.
The legionary helmet, also known as the galea, was a type of helmet worn by Roman soldiers during battle. While it provided protection for the head and face, it was known to be uncomfortable and could impede a soldier's ability to hear and see clearly.
The helmet had a crest and a feathered visor, which could obstruct the soldier's vision, and it was made of metal, which could cause discomfort and restrict hearing. Despite these drawbacks, the helmet was still an important piece of protective gear for the Roman legionaries.
