"The personnel in the helicopter belonged to an “immediate reaction force” that was en route to support troops in contact on the ground, said the NSW member. An immediate reaction force differs from a quick reaction force in that the former is built into the mission plan and is on site during the raid, sometimes circling the action in a helicopter, waiting to be committed if needed, whereas a quick reaction force is typically brought forward from the rear, the NSW source said."

The use of a regular Army Chinook to fly a JSOC mission was “atypical,” the source said. Most JSOC missions involving helicopters are flown by the Army’s 160th Special Operations Aviation Regiment (Airborne).

That must be a relatively new "atypical". Guaranteed, I retired over 10 years ago, but during my time in SF, were very rarely flew on TF160 birds.
