On 17 March 1942, by order of the People's Commissar of Defence (NKO USSR) No. 78, the 75th Naval Rifle Brigade was awarded a Guards title, and on 18 March 1942 converted into the 3rd Guards Rifle Brigade.[4] However, two months later, in May 1942, the brigade was reorganized into the 27th Guards Rifle Division,[5] and all the units, formed as part of this military formation, as well as the division itself, inherit the Guards honorary name of their "ancestor" - the 3rd Guards Rifle Brigade.
One of these guards military units was the 76th Guards Rifle Regiment, formed in the same period as part of the 27th Guards Rifle Division, on the basis of one of the rifle battalions of the former 3rd Guards Rifle Brigade. Subsequently, for the courage and heroism shown by its personnel during the Battle of Berlin, on 11 June 1945 the regiment was awarded the honorary title "Berlin."[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). With the 27th Guards Rifle Division, from 1957 the 27th Guards Motor Rifle Division, it served for decades in East Germany as part of the 8th Guards Army, Group of Soviet Forces in Germany.
In 2011, the brigade was presented with a new type of battle banner.[3] On 4 November 2019, the brigade was given the honorary title Alexandria, and a copy of the regimental standard of the 5th Alexandria Hussar Regiment of the 5th Cavalry Division of the Imperial Russian Army was awarded to the brigade.[9] The title makes it one of several Armed Forces formations that honor formations of the Imperial era, and its Soviet-era honorifics were removed.[10]
The brigade was awarded the honorary Guards title on 9 May 2022 in celebration of Victory Day for its "mass courage and heroism in the defense of the fatherland and state interests in military conflicts," the new title being 15th Separate Guards Alexandriyskaya Motor Rifle Brigade.[11][12]
At the battle of Avdiivka the unit gained prominence for destroying an American M1 Abrams tank.[21] The Lancet drone and FPV drone operators getting most of the credit for the destruction of the Abrams tank.[22]
Karabakh conflict
In November 2020, after a peace agreement ending the war over the region, servicemen from the brigade were deployed to Nagorno-Karabakh to keep the peace.[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.[24] Outside of the servicemen, 90 armored personnel carriers and 380 units of automobile and special equipment were sent with the brigade. The command of the Russian peacekeeping forces was also established in the Karabakh capital of Stepanakert.[25][26][27] On 11 November 2020, Lieutenant General Rustam Muradov was appointed the commander of the peacekeeping forces.[28] On 13 December, the brigade's peacekeeping contingent took control of Hin Tagher.[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." Particularly, General Muradov's meeting with senior Artsakh figures, and the presence of the Artsakh flag at Muradov's meetings had resulted in negative reactions from the Azerbaijanis.[30]
