Yeah, I see someone else clued you in to their existence upthread. Here's an example of one:
https://www.nsa.gov/portals/75/documents/news-features/decla...
It's not a "laundry list of what's classified". It's how you determine what needs to be classified. The DOD's classification guides will absolutely deem information of this nature - attack timing, specific aircraft, intelligence details indicating tracking and confirmation of specific targets, etc. - to be classified.
(They are also, themselves, classified information. For you to get access to the specific one here, it'd have to be voluntarily declassified... by the folks currently trying to cover their asses. Example here: https://www.dni.gov/files/documents/FOIA/DF-2015-00044%20(Do... - note the SECRET//NOFORN original classification of it, and "The public release of the Guide or any portion of the Guide is prohibited." on page 7.)

How did you evaluate that objectively without a guide?
In what world would "1345: 'Trigger Based' F-18 1st Strike Window Starts (Target Terrorist is @ his Known Location so SHOULD BE ON TIME — also, Strike Drones Launch (MQ-9s)" not be a piece of classified information? If revealed, every likely target in Yemen would be potentially forewarned.

"NBC News first reported that the launch times and bomb drop times of U.S. warplanes about to strike Houthi targets in Yemen — details multiple officials have said are highly classified — came from the secure channel."

"'This information was clearly taken from the real time order of battle sequence of an ongoing operation. It is highly classified and protected,' said Mick Mulroy, a former Marine who was the Pentagon’s top official for Middle East policy during the first Trump administration."
