Nationalists 

First of all this is not a place for your pro terrorist nazi separatist propaganda, "Kosovans" don't and never existed if you mean Serbians in Southern Serbia (Kosovo) then yes. Anyway article claims Guard is formed of nationalists. Serbian nationalists, and Serbian nationalist parties together with Serbian nationalist organization absolutely don't support this organization and claim that all military actions should be made by Serbian army (that unlike Guard who had only 11.000 members, has 300.000 members including volunteer, Serbian PVO and SAF, paramilitary, professionals and reserve). Serbian nationalist organizations like Наши, 1389, Српске Двери, Србија до Токија, Српски Националисти etc. also support that all actions in South Serbia (Kosovo) should be done by Serbian army. So I don't think we should put nationalist, but I still won't remove it.
