In the Corps, we call them Sherpa drops. Witnessed three of them used to resupply us near the Syrian border in 2004. The require a logistics tail though to retrieve the equipment and parachutes after the drop is done (at least in a semi-permissive environment). They could absolutely be utilized for in-extremis resupply and left behind as required.
We have utilized helicpopters to deliver fuel, food, and water to forces in the battlespace during this rotation, but aerial resupply is dicey when you add up weather, limited visibility flight qualifications, etc.
