5th Kozara Light Infantry Brigade Insignia
Made popular by the songs of Rodoljub Roki Vulović, the Fifth Kozara was a Serbian Military brigade consisting of multiple infantry battalions and a host of other support units. I have yet to find an original or reproduction patch from this unit for sale, so this will likely be your only shot at snagging one of these rare patches.
3.5 inches wide. Velcro backed and ships with a backer that can be sewn onto items and used to attach similarly sized patches.
