Internal Troops of Ukraine in the context of "Rear (military)"

The National Guard of Ukraine (NGU; Ukrainian: Національна гвардія України, romanized: Natsionalna hvardiia Ukrainy, IPA: [nɐts⁽ʲ⁾ioˈnɑlʲnɐ ˈɦwɑrd⁽ʲ⁾ijɐ ʊkrɐˈjinɪ]; abbr. НГУ/NHU [ˌɛnɦeˈu]) is the Ukrainian national gendarmerie and internal military force. It is part of the Ministry of Internal Affairs, responsible for public security. Originally created as an agency under the direct control of the Verkhovna Rada on 4 November 1991, following Ukrainian independence, it was later disbanded and merged into the Internal Troops of Ukraine in 2000 by President Leonid Kuchma as part of a "cost-saving" scheme. Following the 2014 Revolution of Dignity, amidst the Russian intervention, the National Guard was re-established, and the Internal Troops were disbanded.

The purpose of the National Guard is to serve as a military unit with law enforcement powers. Its mission is to ensure state security, protect state borders (supporting the State Border Service), participate in activities to neutralize paramilitary armed groups, terrorist organizations, organized groups and criminal organizations, protect critical infrastructure such as Ukraine's nuclear power plants, diplomatic missions, and buildings of the Ministry of Internal Affairs. The NGU has sent personnel to UN peacekeeping missions. During peacetime the National Guard focuses on civilian public security, combating organized crime and controlling civil unrest. During wartime the National Guard can be mobilized as a regular military force and take part in combat operations alongside the Armed Forces of Ukraine, which it has done during the war in Donbas and the 2022 Russian invasion of Ukraine.

Internal troops, sometimes alternatively translated as interior troops or interior ministry forces, are a paramilitary and gendarmerie-like law enforcement services, which are found mostly in the post-Soviet states, primarily Russia. Internal troops are subordinated to the interior minister (and interior ministries) of their respective countries.

Perhaps the most prominent example since the Soviet era have been the Internal Troops of Russia (until 2016). Other countries that have had such forces include: Ukraine (until 2014), Georgia (until 2004), Kazakhstan (until 2014), Kyrgyzstan, Azerbaijan, Belarus, Bulgaria (until 1991), Turkmenistan, and Tajikistan. Mongolian internal troops are officially a reserve force in the Mongolian Armed Forces.
