The M-77 Oganj is a 128mm self-propelled multiple rocket launcher developed in the former Yugoslavia. NATO designation is the YMRL-32
Development started in 1968. Prof. Obrad Vucurević, Mechanical Engineer at the time, and Chief operating officer of the Artillery department of Military Technical Institute Belgrade, developed and managed construction and production of the M-77 Oganj.
The prototype, based on a FAP 2220 6x6 truck, was shown to the public for the first time in 1975. Serial production started two years later. The M-77 is mounted on FAP 2026 BDS/A 6x6 truck bed. The rocket system is placed on the back of the platform with 32 128mm launch tubes capable of reaching targets 20,600 metres away. The crew consists of five men.In 1994 Serbia developed new version called Oganj C with designation M94. Oganj C(M94) could fire two type of rockets M91 (cluster-type warhead) and M77 (HE warhead).

M-77 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It starts in US 2 near Blaney Park north of Lake Michigan. The highway borders the eastern edge of the Seney National Wildlife Refuge and passes through the community of Germfask. At Seney, it overlaps M-28 to cross the Fox River before returning northward. The northern half has been designated as a Scenic Spur of the Lake Superior Circle Tour. M-77 runs along the eastern end of the Pictured Rocks National Lakeshore and terminates in Grand Marais north of H-58 near Lake Superior. Originally designated by 1919, the highway has not been changed much in its history. By the late 1950s, the highway was paved, completing the modern M-77 highway.
From US 2 near Blaney Park going north, M-77 runs past the former Blaney Park Resort and out of town by a small private airport next to Lake Ann Louise. The highway continues through rural woodlands past Chip Lake. The road crosses the Manistique River as it runs through Germfask. From just south of Germfask to just south of Seney, the road forms the eastern boundary of the Seney National Wildlife Refuge.
