of Defense, some of the disbanded divisions were reformed from already existing brigades, while others, like the 144th Guards Motor Rifle Division were reformed from scratch. Some units, like the 80th Arctic Motor Rifle Brigade, are trained especially for a specific environment. As of 2022, there were 9 motor rifle divisions, 22 motor rifle brigades and one independent motor rifle regiment, the 7th Independent Guards "Proletarian Moscow-Minsk" Motor Rifle Regiment in the Kaliningrad Oblast. The Navy also has several motor rifle formations under its command in the Ground and Coastal Defence Forces of the Baltic Fleet, the Northeastern Group of Troops and Forces on the Kamchatka Peninsula and other areas of the extreme northeast, apart from traditional naval infantry units. The best-known of these formations is the 126th Coastal Defence Brigade. Also present are a large number of mobilisation divisions and brigades, known as "Bases for Storage of Weapons and Equipment", that in peacetime only have enough personnel assigned to guard the site and maintain the weapons. The Tank Troops are the main impact force of the Ground Forces and a powerful mean of armed struggle, intended for the accomplishment of the most important combat tasks. In 2007, there were three tank divisions in the force: the 4th Guards "Kantemirovskaya" and 10th Guards "Uralsko-Lvovskaya" within the Moscow Military District, and the 5th Guards "Don" in the Siberian MD. The 2nd Guards "Tatsinkaya" Tank Division in the Siberian Military District and the 21st Tank Division in the Far Eastern MD were disbanded in the early 2000s, although the first one is still represented in the ground forces though the 5th Separate Guards "Tatsinkaya" Tank Brigade. Like motor rifle divisions, all tank divisions were transformed into brigades following the 2008 reforms, although the 4th Guards Tank Division was reformed in 2013, with two new tank divisions, the 90th Guards and the 47th Guards being created from pre-existing brigades in 2016 and 2022, respectively. The 10th Guards Tank Division is still represented in the ground forces though the 1st Separate Uralsko-Lvovskaya Tank Brigade. As of 2022, there were 3 tank divisions and 2 tank brigades. The Artillery and Rocket Forces provide the Ground Forces' main firepower. The Ground Forces previously included six static defence machine-gun/artillery and field artillery divisions. The only remaining unit of this type is the 18th Machine Gun Artillery Division The previous 34th Guards in the Moscow MD, 12th in
