Brigadier
That reminds me of 湘军, 淮军, 甘军 etc. in late Qing dynasty. They are not part of the official state army system (green banner and eight banner), but recruited and established by people who were not even government officials but only later appointed. They fought better than the state army. In today's concept, they would be called PMC. But among Chinese they are just part of the army like green banner and eight banner.
I think the notion of PMC is just a western attempt to demonize Wagner due to the reputation of Blackwater etc. Wagner in essence is like elite/special unit in the army with better training and equipment and specialized in urban warfare.
That's what's worrying though, a military force that in theory is answerable only to itself.
Sure they may prove useful in the current conflict, but afterwards?
