Question regarding AM bloodbrothers detachments limitations

[Many in Arms One in Mind]

Simple question Can GC take a mix of units from the intire AM army selection (within the detachment restrictions) or I'm I limited alone to the the sub sections like MILITARUM AUXILlA, AERONAUTICA IMPERIALIS, MILITARUM TEMPESTUS ect. I want to do mass ogryn support and elements valkyries and tanks, is that legal?

The way I read it is that you can take a detachment of stuff, where everything has to have the AM keyword. So you can take scions, ogryns and conscripts led by priests if you want.
