Formation In 2018, the brigade, known as the 100th Separate Brigade of the Territorial Defense Forces (uk 100-та окрема бригада територіальної оборони 100-ta okrema bryhada teritorialʹnoï oboroni), was formed in Volyn Oblast in order to serve as a defense unit for the area.100-та окрема бригада територіальної оборони – Сили територіальної оборони ЗСУ Сили територіальної оборони ЗСУ 2022-11-21 https://tro.mil.gov.ua/brigade/100-ta-okrema-brigada-teritorialnoyi-oboroni/ uk 2024-05-31 According to the Ukrainian Territorial Defense Forces, it was an important part of the Defense Forces, and helped to defend the country's independence. Reforms It was announced on 30 March 2024, by the brigade's press service, that the brigade was being reorganised under the designation of the 100th Mechanized Brigade, being transferred to the Ground Forces component rather than the Territorial Defense Forces. The brigade was only reformed on the basis of the existing units of the 100th Territorial Defense Brigade. Alongside this, the brigade received a new insignia, shifting away from the Territorial Defense Forces styled insignia, opting for the middle of the insignia to have a shield embedded with a fortified tower in the centre. Insignia According to the Territorial Defense Forces of Ukraine, the insignia of the brigade reflected the pride and courage of the defenders of Volyn. The sleeve insignia had the appearance of a red heraldic shield with a blue serrated head and decored with blue edging. The centre of the insignia was embdedded with a silver Latin cross on a red shield. It was mentioned that the red symbolises the bravery, courage and willingness to give one's life for "God and the Motherland", and white represents "purity and integrity". After the brigade was reformed into a mechanized brigade on 30 March 2024, the insignia of the brigade changed to have a fortified castle tower displayed in the centre of the insignia with a subdued green in the background—the tower being a direct reference to a tower of Lubart's Castle in Lutsk, Volyn Oblast. The rest of the shield retained the silver Latin cross on a red shield and was accompanied by a black border.Facebook Facebook https://www.facebook.com/photo/?fbid=406380545342357&set=a.113090384671376 2024-06-01 Later the same day, the insignia was changed for the a second time to have a similar appearance, but instead the centre of the insignia had a light blue colour behind the fortified castle tower, followed by a strikingly different and more purple colour on the borders of the insignia; this variant would remain in use until 25 April 2024 where it would be changed to its current state.Facebook Facebook https://www.facebook.com/photo/?fbid=406608988652846&set=a.113090384671376 2024-06-01 On 25 April 2024, the insignia of the brigade changed for a final time where the design of the Lubart Castle tower was made to be grey rather than a toned and subdued golden/yellow colour, along with the background colour of the tower being returned to the first design on 30 March 2024, being a subdued green. In addition to this, the interior shield in the middle of the insignia had its border colours returned to black, alongside the rest of the shield having a more subdued green border.Facebook Facebook https://www.facebook.com/photo?fbid=421305973849814&set=a.113090384671376 2024-06-01 The insignia still retains the core areas of the insignia, such as the Latin silver cross. Visual insignia Issues and criticisms In a report by Forbes in late April 2024, it was stated that the brigade is one of the newest and most lightly equipped in the entire Ukrainian Ground Forces. The report also mentioned that the brigade was unsuitable for the frontline conditions that commanders required.Axe David Ukraine Had No Choice But To Deploy One Of Its Least-Prepared Brigades Forbes 2024-04-24 https://www.forbes.com/sites/davidaxe/2024/04/24/as-russian-troops-broke-through-ukrainian-lines-panicky-ukrainian-commanders-had-no-choice-but-to-deploy-one-of-their-least-prepared-brigades/ 2025-04-23 This came after the 115th Mechanized Brigade were pulled away from Ocheretyne for its reported poor performance, with many including DeepStateMap.Live holding the 115th Mechanized Brigade accountable for the loss of the settlement.Ukraine's 115th Mechanised Brigade reveals how it defended Ocheretyne from intense Russian advance Ukrainska Pravda 2024-05-02 https://www.pravda.com.ua/eng/news/2024/05/2/7453992/ 2024-06-01Telishevska Sofiia The 115th brigade denies its responsibility for the collapse of the defense of Ocheretyne Бабель 2024-05-02 https://babel.ua/en/news/106711-the-115th-brigade-denies-its-responsibility-for-the-collapse-of-the-defense-of-ocheretyne 2024-06-01Ukrainian brigade denies responsibility for the fall of Ocheretyne Ukraine News Premier Independent English-language Source — The New Voice of Ukraine 2024-05-02 https://english.nv.ua/nation/ukrainian-brigade-denies-responsibility-for-the-fall-of-ocheretyne-50415196.html 2024-06-01 Equipment Vehicles On 8 July 2024, it was reported in an article by David Axe that the 100th Mechanized Brigade had been equipped with German 1A3 Marder infantry fighting vehicles, reportedly giving the brigade its first major protected mobility and firepower.
