The 15th Separate Guards Motor Rifle Alexandria (Peacekeeping) Brigade (Russian: 15-я отдельная гвардейская мотострелковая Александрийская бригада (миротворческая), romanized: 15-ya otdel'naya gvardeyskaya motostrelkovaya Aleksandriyskaya brigada (mirotvorcheskaya)), Military Unit Number 90600, is a unit in the Russian Ground Forces.

The regiment traces its history back to the 75th Naval Rifle Brigade, formed during the Great Patriotic War from 29 October 1941[3] to December 1941,[4] in Novokazalinsk in the Kazakh Soviet Socialist Republic.

"[6] On 5 October 1945 it is transformed into the 69th Guards Mechanised Berlin Red Banner Order of Kutuzov Regiment; and in 1957 into the 243rd Guards Motor Rifle Berlin Red Banner Order of Kutuzov Regiment (Military Unit Number 47290).

In 1991, the 27th Guards Motor Rifle Division was withdrawn from the Western Group of Forces and redeployed to Totskoye in the Volga-Ural Military District.

The current brigade was formed on 1 February 2005 by redesignation of the 589th Guards MRR, in accordance with a directive of Minister of Defence Sergei Ivanov given on 30 December 2004.

[8] Servicemen of the brigade have also been part of the peacekeeping contingents by decision of the President of Russia under the Commonwealth of Independent States, the Organization for Security and Co-operation in Europe, and the Shanghai Cooperation Organisation.

[23] In the agreement, 1,960 servicemen of the brigade were to be sent to the region, leaving from Ulyanovsk Vostochny Airport on a Il-76 military transport aircraft.

[29] In early 2021, Azerbaijani authorities accused the unit of "a pro-Armenia attitude, instead of taking the required neutral stance for the implementation of the peace agreement."
