Vojska Srbije patches

Here are the ones my uncle has in black, he has also the blue ones like in one of the upper posts. If anyone know more about them, please let me know...he was there by the end when the special forces were abolished, he just served in the yugoslav peoples army, therefor the red star i guess. The red star is also on the blue ones i mentioned before. So this badges existed definitely before 1992. My guess is that at the end of communism they just get rid of th red star, since the design looks identical....my uncle told me that a special forces navy diver had to go through training for over a year, which included the diver/explosives under water training cause it was apparently the most difficult of the 3, then parachute training, then mountain training....
