The fall of Rome
One of the causes that led to the fall of Rome was the invasions. but the soldiers were not as trained as highly trained as the earlier soldiers. this was because in the earlier years Rome hired mercenaries to fight for them. (foreign soldiers serving for pay) most were Germanic warriors who had little loyalty to Rome. Also maintaining an army was a very bug drain on Government and Economy, many frustrated Romans lost interest to fight

The United States
The difference between Roman military and the United states military today is that we are far more advanced in the fields of tactics, Technology, and weapons. We are also similar in some areas, for example our military spends about 530 billion a year and the Romans basically drained their economy because of foreign spending.
