Final answer:
The military played a significant role in the fall of the Western Roman Empire due to reliance on barbarian mercenaries, internal divisions, and resource shortages.
Step-by-step explanation:

One aspect was the heavy reliance on barbarian mercenaries, who became increasingly influential and even took control of the empire's military forces. The military's internal divisions and constant power struggles further weakened the empire. Additionally, as the empire's resources dwindled, it became harder to maintain a strong military presence in the face of external threats.
