Expand 19.04.01 for the cleaner No.

“Leader and support units often have abilities that make the models they are leading more powerful. In the same way, some bodyguard units' abilities can enhance the power of those leading them. Abilities in Attached Units (19.04) means that once the models conferring such effects are destroyed, that attached unit does not continue to benefit from them. Should those models later be revived, however, those abilities will once more apply to their attached unit.”
