All of the aerial resources on the fire are working for an air tactical group supervisor (ATGS). Beneath the ATGS is a lead plane that serves as the Airtanker coordinator. The aerial resources never contact the IC directly unless there is some sort of safety issue, or they cannot contact the ATGS (often called "Air Attack").
What you heard was not confusion, just a HUGE attack from the air post Esperanza Fire. There was a large number of airtankers and helicopters, one ATGS platform, and one lead plane operating within a very small airspace.... on a relatively small fire.... in the East Fork of San Gabriel Canyon.
The USFS and the LACoFd work together on fires year-round.
