Serbian WW1 Army Blanket

[paja]

According to family history ancestor brought this blanket home after the war ended. My grandmother was using it for ironing for decades hence the brownish burn marks. 
Can anyone confirm that it really is a Great War military issue blanket? I've being doing some online research and looks like the Americans used something very similar, perhaps part of foreign help?
