It's a bit of both.
Basically the rangers are all the same type; the groups are the same.
Their overarching training and information sharing is the same. There may be anomalies across different CRPGs because of the remoteness of a community or the position of a community, or the activity within that CRPG. There may be different levels of training, dependent on operational tempo, or needs and desires of the department. However, the general macro overview is the same for all rangers.
