Yesterday, it was told that Serbian Army, as an aid by United States of America, have received a "MILES" system, for the efforts (and for the exercising) in multinational operations.
2 days ago, I also read about US base that will be opened in the Southern Serbia, which purpose is "training camp for everyone who take part in multinational operations"...
We all are being eventually absorbed into NATO standards since this is the monopoly for "multinational operations" in the Western world. You don't get a clearance for out country ops unless you meet the requirements or you go PMC.
While I personally despise them a tad I somewhat respect their persistence in the world of survival in spite of significant publicity failures. US has its camps all around Europe and opening up another one in Serbia ain't a major occurrence.
