The Hessians
Germany sent over highly trained soldiers called Hessians. Washington attacked the Hessian stronghold at Trenton on Christmas Day. Without losing a soldier, the American Army defeated the Hessians. This victory gave the Americans a new strength to fight on, as well as needed supplies, clothing, ammunition, and food. The Hessians were known as the best trained soldiers in the world and were utterly vicious in battle.
They're called mercenaries.

Mercenaries
Basically for reinforcement and special skills. Although the Romans could levy plenty of troops from Italy, some of their allies had specialities that were useful such as slingers, bowmen and cavalry which could reinforce the Roman units. An example of this is their Batavian allies who were not only excellent horsemen, but they prided themselves on being able to swim across a river in full armor.
British mercenaries were soldiers that fought for pay and were not a regular part of the army. Mercenaries were an important part of some of Britain's early war efforts, though they are seldom used today.
