How does OAM differ from the U.S. Coast Guard?

In general, OAM's law enforcement authorities extend to the U.S. customs waters and land/riverine border environments, while the U.S. Coast Guard's law enforcement authorities extend from U.S. waterways and marinas outward into international waters. Both operate marine and air assets, however. Unlike OAM, the U.S. Coast Guard can use its Title 10 authority to operate as a member of the armed services under military chain of command.
