The 27th Separate Guards Sevastopol Red Banner Motor Rifle Brigade "60th Anniversary of the USSR" (Russian: 27-я отдельная гвардейская мотострелковая Севастопольская Краснознамённая бригада имени 60-летия СССР, romanized: 27-ya otdel'naya gvardeyskaya motostrelkovaya Sevastopol'skaya Krasnozamyonaya brigada imeni 60-letiya SSSR) is a tactical formation of the Russian Ground Forces.

By the summer, the Soviet General Staff had developed a draft of new Combat and Field Manuals for the Ground Forces, more in line with the post-war era.

The unit served as the 404th Guards Motorised Rifle Regiment (404th GMRR) from 1957 until the early 1980s, and in 1982 was given the honorific title "named for the 60th anniversary of the Union of Soviet Socialist Republics", celebrated that year.

[7] After the Russian withdrawal from northern Ukraine, the 27th Brigade was redeployed to the area of Izium, where it remained until a September 2022 Ukrainian counteroffensive across Kharkiv Oblast, which forced it to retreat.
