Let’s see where else…
1 Gaza
2 Azerbaijan quite extensively
3 Syria
4 China
5 Russia
6 several countries in Africa
7 Mexico
8 Haiti
9 Venezuela
10 major defense companies
11 DPRK potentially in future
Some are those against infantry specifically, since you seem to want to narrow the focus. Exhibits 1 and 2 are telling. Some are used more broadly than that. Exhibit 5 some might consider a new leg of nuclear deterrence. Exhibit 7 is nonstate. Exhibit 8 is LE (if you can even call it that). Exhibit 11 has not been used yet, but could result in changes to future planning assumptions for a conflict on the peninsula.
When the USMC is looking at reshaping the composition of its infantry squad due to it, I'd call that a doctrinal change in the DOTMLPF sense. I don't think drones are going away, they've routinely defeated armored vehicles in Ukraine that we used extensively in ODS '91/OIF '03, and I do think they've begun to change warfare doctrine.
I would say yes, drone warfare has already revolutionized warfare.
Don't back track.
Drones have been around the military since the 1980s (as you mentioned). Tell us why you think they're the raison d'être of the current/ongoing RMA. Listing conflicts where they've been used doesn't make them decisive. I could point out several other methods of conventional force employment in those conflicts that had unforeseen utility.
