The704th CBRN Protection Brigade (MUN A0807) is abrigade of theUkrainian Support Forces of theArmed Forces of Ukraine. And the only separate formation of the Radiological, Chemical, and Biological Protection Troops within theGround Forces of Ukraine.
In 1992 when the Radiological, Chemical, and Biological Protection Troops within the Armed Forces of Ukraine were established, they numbered five brigades and 15 similar battalions of this type. All of the brigades and battalions apart from the704th Detached Regiment were eventually disestablished.
In July 2007, the regiment was fulfilling the task on eliminating the consequences of the accident at the Ozhidiv-Krasne railway line of the Lviv Railway (uk:Фосфорна аварія під Ожидовом), where 15 tanks with yellow phosphorus were upturned.
The disbandment of the unit, as part of the reorganisation of the Ukrainian Army, started in 2013. The military property (machines, garages, hangars) was sold, and personnel dismissed or transferred to other units. In December 2013, the last 20 CRM-4 (Chemical Reconnaissance Machine) vehicles based on armored personnel carrier (BTR-80) were sent to Crimea. In total, there were about 50 of them in the Unit.[1]
With the beginning of theRusso-Ukrainian War in 2014, regiment personnel with machine guns and sapper shovels in their hands took part in the protection of the territorial integrity of Ukraine.[1]
In June 2015, the 60th anniversary of the704th Regiment of Radiological, Chemical and Biological Protection was celebrated.[2]
As of 2017, the regiment is not considered a combat unit and participates in operations mostly on the second and third lines of defence.[1]
