There's a difference. SEALs are simply the special forces division of the Navy. MACOs are an entire military branch. An entire military branch being twice as hard to get into than a special forces unit is a little much, especially in a utopia paradise where the MACOs are supposedly the only military branch. That is, the only one anyone admits to being military.According to Military.com, only about 6 percent of SEAL applicants make it. MACO is twice as hard.
