The patriots had the advantage of being on their home land which the british didn't have, they had to be sent from england on ships. A disadvantage, however, would be that the british were better trained and had more weapons. Another advantage is the patriots had the more fighting spirit than the british, they had something to fight for, freedom. Another disadvantage is that the british had a better standing army, once some soldiers died, more came om the way.
