Multiple combat techniques

[demos606]

Ok, I pretty much know this is covered *somewhere* but I can't find it after reasonable research so I'm asking here. Certain OCC get multiple hand to hand combat training routines (ie, Scarecrow - assassin and martial arts), does the character get the benefits and bonuses of both regardless which is being used or just the bonuses of the style being used. The closest clarification I can find is Skills and Powers in Ninja's and those can only be used with the style they were learned with unless otherwise stated.

No they don't. They get skill programs that offer different hand to hand combat skills, but they still only get one of the skills.
