I'm not sure that's fair to say, you can recognize patterns, spot and attempt to emulate something, but that doesn't mean you actually are doing it correctly. Lots of militaries try to emulate the US military but cannot. Operational expertise, tempo and other factors are really difficult to nail down and something that's developed over time and with practice.
I think what you're saying is fair, but the only nation state actors with the right combination of evidence, agenda and motives would be Russia. Who else?
