Maybe.
If, as the casebook says, they're all doing the same thing at the same time in reaction to the same thing, then I'd assess a single bench technical which is also charged indirect to the HC. If, however, one ASSistant is yelling about a traveling call, and another ASSistant is at the same time yelling about a foul he thinks should have been called, I'm whacking them both individually, and charging 2 indirects to the HC.
